A nuclear reactor becomes unstable if both safety mechanisms A and B fail. The probabilitiesof failure are P(A) =1/300 and P(B) = 1/200. Also, if A has failed, B is then more likely to fail:P(B/A)=1/100.a) What is the probability of the reactor going unstable?b) If B has failed, what is the probability of the reactor going unstable?

Given that ,We have to find the Probabilities .

A door-to-door salesman expects to make a sale 21% of the time when starting the day. But making a sale increases his enthusiasm so much that the probability of a sale to the next customer is 0.32. If he makes no sale, the probability for a sale to the next customer stays at 0.21. What is the probability that he will make at least two sales with his first three visits?

You are enrolled in MBA 440. At the beginning of the semester, you used your hunch to estimate the likelihood of passing this class. Let P be the event of passing the class; F is the event of failing the class. Your prior probabilities are as follows: P(P)=0.7 P(F)=0.3 After the first week of class, you find out that you have failed the first assignment. Let A1 be the event of passing the first assignment; let A2 be the event of failing the first assignment. Now you feel you need to update your belief about the likelihood of passing this class. You talk to your Professor and she tells you that given someone has passed the class, the probability of passing the first assignment is 0.8, i.e. P(A1|P)=0.8. She also gives you the following conditional probabilities: P(A2|P)=0.2; P(A1|F)=0.3 and P(A2|F)=0.7. What is the posterior probability that you will pass this class given that you have failed the first assignment?
Brian, a landscape architect, submitted a bid on each of three home landscaping projects. He estimates that the probabilities of winning the bid on Project A, Project B, and Project C are 0.7, 0.5, and 0.2, respectively. Assume that the probability of winning a bid on one of the three projects is independent of winning or losing the bids on the other two projects. Find the probability that Brian will experience the following. (a) Win all three of the bids (b) Win exactly two of the bids (c) Win exactly one bid

A door-to-door salesman expects to make a sale 14% of the time when starting the day. But making a sale increases his enthusiasm so much that the probability of a sale to the next customer is 0.39. If he makes no sale, the probability for a sale to the next customer stays at 0.14. What is the probability that he will make at least two sales with his first three visits?
