Unformatted text preview: Y given X = i . 4) Find P ( Y = 0) and P ( Y = 1) Problem 2: Problem 29, p. 89. Hint: After a ﬂip, what is the probability that the next ﬂip is a change over? (very simple solution!) Problem 3: Problem 56, p. 93. Hint: Use the trick X = ∑ i X i we used for Binomial and Hypergeometric. Here let X i = 1 if there is at least one coupon of type i . You will need to ﬁnd the probability that this event occurs. Problem 4: Problem 71, p. 95....
