Unformatted text preview: Independence Please hand in: problems 20, 23, and 26 in Section 1.7 of EPFA . Please also look at problems 19, 31, 33, and 34. Distributions, Expectation, and Variance Please hand in: problems 38, 54, and 55 in Section 1.7 of EPFA . Please also look at problems 35 and 39. Extra Problems 1. Set subtraction A-B is dened by A-B = A B c . Prove that if B A , then A = B ( A-B ) and P ( A-B ) = P ( A )-P ( B ) . Remark: A good way to prove equality of sets C = D is to show C D and D C . And to show C D , one might start with x C and show x D as well. 2. Show that P ( A B ) P ( A ) + P ( B )-1 ....
