A salesperson either makes a sale (S) or does not make a sale (N) with each of two potential customers. The simple events and their probabilities are given below. Simple Event Probability SS 0.08 SN  0.12 NS 0.15 NN 0.65 What is the probability that at least one sale is made?   A. 0.35   B. 0.08   C. 0.65   D. 0.27

A and B are independent events. Use the following probabilities to answer the question. Round to 4 decimal places. P(A) = 0.39,  P(A and B) = 0.31, find P(B)

1. What is the probability that you will pass course b? 2. Are the events I’d paying the courses mutually exclusive? Explain your answer using probabilities.

Let A and B be two events such that the probability of B is 0.5 and the probability of both is 0.2. Find the probability of A given that B occurs.

A couple has two children. Let A be the event that their first child is a boy and note that P(A) = 0.512. Let B be the event that their second child is a girl, with P(B) = 0.488. A and B are independent events. What is the probability that the couple has first child that is a boy and a second child that is a girl?

Given P(A) = 0.10, P(B) = 0.63, P(C) = 0.53 and that events A, B, and C are independent, what is P(A, B, and C). Answer in decimal form.  Round to 3 decimal places as needed.

The events A and B are mutually exclusive. If P(A) = 0.5, and P(B) = 0.3, what is P(A or B)? a. 0.15 b. 0.8 c. 0.2 d. 0
