If x is to be chosen at random from the set {1, 2, 3, 4} and y is to be chosen at random from the set {6, 7}, what is the probability that xy will be even?  Choose the correct choice from the following answers:
A) 1/6
B) 1/3
C) 1/2
D) 2/3
E) 5/6
Probably the best way to solve would be to use 1 - P(opposite event) = 1 - P(odd) = 1 - P(odd)*P(odd) = 1 - 2/4*2/3 = 8/12 = 1/6   1/6nswer: 1/6
