A special deck of cards has 3 purple cards, and 4 yellow cards. The purple cards are numbered 1, 2, and 3. The yellow cards are numbered 1, 2, 3, and 4. The cards are well shuffled and you randomly draw one card.
A = card drawn is yellow
B = card drawn is even-numbered
a) How many elements are there in the sample space?
b) P(A) =
C) P(B)

Powerful women's group has claimed that men and women differ in attitudes about sexual discrimination. a group of 50 men (group 1) and 40 women (group 2) were asked if they thought sexual discrimination is a problem in the united states. of those sampled, 11 of the men and 19 of the women did believe that sexual discrimination is a problem. if the p-value turns out to be 0.035 (which is not the real value in this data set), then at = 0.05, you should fail to reject h0. at = 0.04, you should reject h0. at = 0.03, you should reject h0. none of these would be a correct statement.
