J 2 The ABC contractor has been asked to submit a proposal for developing a new product.The cost of bid preparation is PhP 10,000.00. If ABC submits the proposal, the chances are60-40 that the bid will be accepted. It is not certain that the product can actually bedeveloped, but there are two (2) methods of development. Method I will cost PhP 120,000.00and has 75% chance of success. Method I will cost PhP100,000.00 and the profitabilitysuccess is 45%. If the product is developed, the contract must decide whether to advertiseor not. If advertised, the return will be PhP 1,600,000.00; if not, the return will bePhP1,000,000.00. Should ABC prepare a proposal?

A corporation is selecting where to develop a restaurant with a capital of Php 2,000,000. They can put it in the center of a business district to raise prices, but it will have to compete with other restaurants in the area. They could even establish it in front of a school, where they would have to charge less sincethey would be competing with fewer restaurants.The company analyzed the considerations and data shows that building a restaurant in a commercial district has an 80% chance of earning Php 1 million and a 20% chance of losing the entire capital, whereas building a restaurant in front of a school has a 95% chance of earning Php 500 thousand and a 5% chance of losing the entire capital. Where should the corporation establish the restaurant based on the predicted profit?

A big private oil company must decide whether to drill in the Gulf of Mexico. It costs $1 million (i.e., 1M) to drill, and if oil is found its value is estimated at $6 million. At present, the oil company believes that there is 45% chance that oil is present. Before drilling begins, the big private oil company can hire a geologist for $100,000 to obtain samples and test for oil. There is only about a 60% chance that the geologist will issue a favorable report. Given that the geologist does issue a favorable report, there is an 85% chance that there is oil. Given an unfavorable report, there is a 22% chance that there is oil. The following decision tree determine what the big private oil company should do. All the numbers are represented in a million unit.
A gray mouse has a 30% chance of stealing cheese from a mousetrap without getting caught, while a white mouse has a 10% chance of succeeding at that. If 15 gray mice and 17 white mice try to steal cheese from different traps, how many pieces of cheese would you except them to get away with?
A new restaurant with 134 seats is being planned. Studies show that 57% of the customers demand a smoke-free area. How many seats should be in the non-smoking area in order to be very sure (μ+3σ) of having enough seating there?
Globally, 35% of all ridged brittleshell tortoises have spots on their shells. A herpetologist in Citition collects a sample of 38 ridged brittlesell tortoises and finds that 16 of them have spots on their shells. The herpetologist would like to test the claim that the proportion of ridged brittleshell tortoises in Cititon with spots on their shells is greater than 35%. The herpetologist ends up rejecting the null hypothesis. If the actual proportion of ridged brittleshell tortoises in Cititon with spots on their shells is 41%, then what type of error, if any, has occurred? In the problem above, what is the test statistic?
Medical researchers performed a comparison of two drugs Clopidogrel and ticagrelor, which are supposed to rieduce the risk of a heart attack and stroke in coronary patients. a total of 6676 patients were given clopidogrel and 6732 were given ticagrelor. Of the Clopidogrel patients 668 suffered a heart attack or stroke within one year, of the ticagrelor patients 569 suffered a heart attack or stroke. Can you conclude that the proportion of patients suffering aheart attack or stroke is less for ticagrelor? Use a 1% significance level.
A stock market analyst examined the performance of the shares of a large number ofcorporations. When the performance of these stocks was investigated year later, it turned out that 25 % performed much better than the market average ; 25 % performed much worse ; and remaining shares performed about the same as the average . 40% of the stocks that performed much better than the market average were rated as " good buys ” by the analyst ; as were 20 % of those that did about as well as market average and 10 % of those that did much worse than market average . What is the probability that a stock rated as “ good buys ” by the analyst performed much better than theaverage ?
If parallel components are used for any component with worse than a 1/10000 chance of failure, what is the overall reliability? Parallel components are used for any component with 1/10000 chance of failure, then the reliability is:

An independent research group has been studying the chances that an accident at a nuclear power plant will result in radiation leakage. The group considers that the only possible types of accidents at a reactor are fire, mechanical failure, and human error, and that two or more accidents never occur together. It has performed studies that indicate that if there were a fire, a radiation leak would occur 20 percent of the time; if there were a mechanical failure, a radiation leak would occur 50 percent of the time; and if there were a human error, a radiation leak would occur 10 percent of the time. Its studies have also shown that the probability of A fire and a radiation leak occurring together is 0.0010. A mechanical failure and a radiation leak occurring together is 0.0015. A human error and a radiation leak occurring together is 0.0012. (a)What are the respective probabilities of a fire, mechanical failure, and human error? (b)What are the respective probabilities that a…
UG can only properly release a limited number of games, even though they have a number of candidates in development. They are trying to figure out which game they should release next quarter among four possibilities (and in so doing, gain some insight into how to make such decisions in the future). There is some uncertainty as the projected profitability of the release depends on the state of the gaming market 6 months in the future. Based on their experience, UG has provided an estimate of profit for a “good” gaming market and a “bad” gaming market for the four candidate games (see below). Even with these estimates, though, UG managers are unsure which game to choose. UG managers consider themselves to be optimistic about the future but would like to consider a large variety of ways to make this decision. When asked how likely they think it is that the market will be good, UG said “about a 65% chance”. UG mentioned that they are curious about “opportunity loss”, but they have…
