7. The first part is math. The second part is modeling. = (a) B1, B2, B3 are three events that partition 12. P(B1) = P(B2) P(B3). The distribution of random variable Y is Bin(2, 20) if Bi occurs. If B2 occurs, Y ~ Bin(, 20). If B3 occurs, Y ~ Y ~ Bin(3, 20). Find P(B1Y = 11). (b) A box contains 3 coins, one fair, one weighted with a chance of coming up heads, and one weighted with a chance of coming up tails. You take a coin at random from the box, flip it 20 times, and get 11 heads. What is the probability you have the fair coin?
