1) You are at a party. Wine and beer are being served (to those who are of legal age, of course) amongst other beverages. 15% of the individuals drank wine and beer. 65% of the individuals drank beer. 45% of the individuals drank wine. You randomly select an individual from the party, what's the probability the individual had wine or beer? 4) Suppose a sample was taken to examine student preferences for day of the Suppose all sample points for a sample space are contained within week an exam is preferred. Each student within the sample selected M, W, the following events for both or F. Results indicated M = 38, W = 6, & F = 16. problems below. Class What is the probability of the following: P(M) = ? P(W) = ? P(F) = ? Assignment 2) If given: #21 P(A) = .3 P(MF) = ? P(B) = .1 P(W U F) = ? P(C) = .1 P(E,) = P(E2) = P(E;) = 1/5 P(D) = ? What is P(D)? 5) Use the following Venn Diagram and the sample points known probabilities to find the P(EA) = P(Es) = 1/20 following event probabilities. P(E6) = 1/10 P(E7) = 1/5 3) If given: P(A) = P(B) = .4 P(A) = ? A B P(C) = ? P(A U B) = ? E1 Ez P(D) = .1 What is P(C)? P(AC) = ? E3 Es E6 E4 20 Lecture 3.2-3.4 P(AC ( B)= ? E7
