- The conditional probability of E given that F occurs is P(EF)=___________. So in rolling a die the conditional probability of the event E, getting a six, given that the event F, getting an even number, has occurred is P(EF)=___________.arrow_forwardAssume that the probability that an airplane engine will fail during a torture test is 12and that the aircraft in question has 4 engines. Construct a sample space for the torture test. Use S for survive and F for fail.arrow_forwardIf a binomial experiment has probability p success, then the probability of failure is ____________________. The probability of getting exactly r successes in n trials of this experiment is C(_________, _________)p (1p)arrow_forward
- Suppose X is binomially distributed with parameters n and p; further suppose that E(X) = 5 and Var(X) = 4. Find the n and p.arrow_forwardThe amount of time it takes Lexie to wait for the bus is continuous and uniformly distributed between 3 minutes and 16 minutes. What is the probability that it takes Lexie between 6 and 7 minutes given that it takes less than 11 minutes for her to wait for the bus? Provide the final answer as a fraction.arrow_forwardSuppose that x has a hypergeometric distribution with N = 300, n = 30, and K=100. 1. Find p(x=10) by using the hypergeometric distribution. 2. Find p(x=10) by using the approximate binomial distribution. 3. Is the binomial approximation reasonable?arrow_forward
