Probability of At Least One Let A = the
a. P(Ā) = (0.95) (0.95) (0.95) = 0.857
b. P(A) = 1 − (0.95)(0.95)(0.95) = 0.143
c. P(A) = (0.05)(0.05)(0.05) = 0.000125

- (a) An experiment has two outcomes, "success" and "failure„" where the probability of success" is p. The experiment is performed n times. What of probability is with this experiment? (b) What is the probability that success occurs exactly r times? (c) An archer has probability 0.6 Of hitting the target. find the probability that she hits the target exactly 3 times in 5 attempts-arrow_forwardConditional probability If 40 of the population have completed college, and 85 of college graduates are registered to vote, what percent of the population are both college graduates and registered voters?arrow_forwardConditional probability About 25 of the population watches the evening television news coverage as well as the soap operas.

- Spread of a Virus A medical researcher is studying the spread of virus in a population of 1000 laboratory mice. During any week, there is an 80 probability that an infected mouse will overcome the virus, and during the same week there is a 10 probability that a noninfected mouse will become infected. Three hundred mice are currently infected with the virus. How many will be infected a next week and b in 3 weeks?arrow_forwardBackup System A space vehicle has an independent backup system for one of its communication networks. The probability that either system will function satisfactorily during a flight is 0.985 what is the probability that during a given flight (a) Both systems function satisfactorily, (b) Both systems fail, and (c) At least one system functions satisfactorily?arrow_forwardReliability of a Machine A machine that is used in a manufacturing process has four separate components, each of which has a 0.01 probability Of failing on any given day. If any component fails, the entire machine breaks down. Find the probability that on a given day the indicated event (a) The machine breaks down. (b) The machine does not break down. (c) Only one component not fail.arrow_forward
- Dividing a JackpotA game between two players consists of tossing a coin. Player A gets a point if the coin shows heads, and player B gets a point if it shows tails. The first player to get six points wins an 8,000 jackpot. As it happens, the police raid the place when player A has five points and B has three points. After everyone has calmed down, how should the jackpot be divided between the two players? In other words, what is the probability of A winning and that of B winning if the game were to continue? The French Mathematician Pascal and Fermat corresponded about this problem, and both came to the same correct calculations though by very different reasonings. Their friend Roberval disagreed with both of them. He argued that player A has probability 34 of winning, because the game can end in the four ways H, TH, TTH, TTT and in three of these, A wins. Robervals reasoning was wrong. a Continue the game from the point at which it was interrupted, using either a coin or a modeling program. Perform the experiment 80 or more times, and estimate the probability that player A wins. bCalculate the probability that player A wins. Compare with your estimate from part a.arrow_forwardSpread of Disease Health authorities estimate that of the raccoons in a certain rural county are carriers of rabies.
