Prоblem 2 (20 pоints) A new frоzen food product will ultimаtely turn out to be а fаilure in the market (A1), a marginal success (A2), or a major success (A3). These are the outcomes of interest. It is known from past experience with similar products that the prior probabilities are P(A1)=0.7, P(A2)=0.2, and P(A3)=0.1. The product was introduced in a test market to see whether it would achieve a small market share (B1) or a large market share (B2) in the test market. It was found that P(B1|A1)=0.02, P(B1|A2)=0.24, and P(B1|A3)=0.98 Formula: P (A∩B) = P (B∩A) = P (B) *P (A|B) or P (A) *P (B|A) a. What is a probability that P(A1 | B1) ? (10 points) b. What is a joint probability of (A2) and (B2)? (10 points)
