Stat 1051 lecture 9 chapter 3 and part of chapter 4 (september 26) For any two events, a and b. Suppose a box contains 3 white and 2 blue marbles. Pick 2 marbles at random, find the probability that both are white. Picking 2 marbles at random is equivalent to picking one after another without replacement. There is a 30% chance(you have to convert to percent cause that is what probability is) that both the marbles that are picked are both white. C ) = p(a) x p(b|a) x p(c|a . Two events a and b are said to be independent if the probability of an event a does not depend on whether event b has occurred or not. P(a|b) = p(a) and p(b|a) = p(b) A and b are independent if and only if p(a . P(snow in both cities) = p(b . If a number of values are independent then p(
