Determine whether the distribution is a discrete probability distribution.-~~P(x) Q0.160.210.260.210.16 Is the distribution a discrete probability distribution? Why? Choose the correct answer below.O A. No, because some of the probabilities have values greater than 1 or less than 0.O B. Yes, because the probabilities sum to 1 and are all between 0 and 1, inclusive.O C. Yes, because the distribution is symmetric.OD. No, because the total probability is not equal to 1.

An antique collecter has been following the price of a certain old camera and he found out that the camera's price changes each day and it can either rise or fall in value. The price changes per day are assumed to be independent events. After observing the price for 8 months, he found out that the price rose for 40% of the days and it sunk for the rest. He wants to determine the probability that the camera will be a certain value on a particular day so he asked you for help. 1) What distribution does this problem follow? (Geometric, Binomial, Poission?) 2) Determine the probability that 7 days from now, the cost of the camera will be the same as it is today.3) Determine the probability that the camera's cost has increased from its current value after 5 days.

Daniel is 1000 meters from his home and decides to walk home. Every time he takes one step, he goes forward 1 meter with a probability of 2/3 and backwards 1 meter with a probability of 1/3, regardless of the steps taken earlier. (a) Calculate the expected value of the distance to his home after 1000 steps. (b) Calculate approximately the probability that Daniel, after 1000 steps have come at least 300 meters closer to his home. Plz explain.
Before every flight the pilot must verify that the total weight of the load is mess than the max allowable load for the aircraft. The aircraft can carry 43 passages, and a flight has fuel and baggage that allows for a total passenger load of 7,095 lbs. The pilot sees that the plane is full and all the passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 7,095/43= 165lbs. What is the probability that the aircraft is overloaded? Should the pilot take any action to correct for an overload aircraft? Assume that the weights of men are normally distributed with a mean of 174.4lbs and a standard deviation of 39.6
An engineer uses three machine's concrete to pore a concrete rode. The first one produces 60% of total production and has a failure ratio of 4.5% while the other two machines have the same percent of production and failure ratio. If the probability of drawing sample to be provided from the third machine is 0.2857, so 1- What is The failure ratio of the second machine? 2- What is The percentage probability of drawing sample to be provided from the first machine?

Choose a postmenopausal woman at random. The probability is 0.32 that the woman chosen has osteopenia (low but not pathologically low bone density ) and 0.04 that she has osteoporosis (pathologically low bone mineral density).(A.)What is the probability that a randomly chosen postmenopausal woman has a healthy bone density? Please use 2 decimal places (B)What is the probability that a randomly chosen postmenopausal woman has some problem with low bone density (osteopenia or osteoporosis)? Please use decimal places.
A construction company employs two sales engineers. Engineer 1 does the work of estimating cost for 70% of jobs bid by the company. Engineer 2 does the work for 30% of jobs bid by the company. It is known that the error rate for engineer 1 is such that 0.02 is the probability of an error when he does the work, whereas the probability of an error in the work of engineer 2 is 0.04. Suppose a bid arrives and a serious error occurs in estimating cost. What is the probability that Engineer 1 did the work?
