Sample text

A card is chosen at random from a deck of 52 cards. Let A be the event that the card is an ace, and B, the event that it is a club. Then P(A)=f2 =^ P{B) = g = l and P(AB) = P {ace of clubs} = ^ , so that A and B are independent. Example 3. Consider families with two children, and assume that all four possible distributions of gender: BB, BG, GB, GG, where B stands for boy and G for girl, are equally likely. Let E be the event that a randomly chosen family has at most one girl, and F, the event that the family has children of both genders.

A sample of size 8 is selected at random without replacement.

A) If F is the DF defined in Problem 3(a), find P{X > \], P{\ < X < §}. (b) If F is the DF defined in Problem 3(d), find P{-oo < X < 2}. 4 DISCRETE AND CONTINUOUS RANDOM W U A B L E S Let X be an RV defined on some fixed but otherwise arbitrary probability space (£2,5, P), and let F be the DF of X. In this book we restrict ourselves mainly to two cases: the case in which the RV assumes at most a countable number of values and hence its DF is a step function, and that in which the DF F is (absolutely) continuous.
