Unformatted text preview: many freshman girls must be present if sex and class are to be independent when a student is selected at random? 4) Suppose that you continually collect coupons and that there are m different types. Suppose also that each time a new coupon is obtained it is a type i coupon with probability p i , i= 1, … ,m . Suppose that you have just collected your n th coupon. What is the probability that it is a new type? 5) Independent trials that result in a success with probability p and a failure with probability 1-p are called Bernoulli trials. Let P n denote the probability that n Bernoulli trials result in an even number of successes( 0 is considered as an even number) a. Show that P n = p(1- P n-1 ) + (1-p) P n-1 n ≥ 1 b. Use part a) to prove that P n =[1+ (1-2p) n ]/2...
