S = { 1,2,3,5,6}
T = { 2,3,6,7 }
what is the probability that x chosen from S and y chosen from T will result x*y = even Choose the correct choice.
A) 2/7 B) 3/8 C) 7/10 D) 10/7 E) 3/8
p: the probability that x*y is even, then p=1-p(x*y is odd)   p(x*y odd)=p(x odd)*p(y odd)=3/5*2/4=3/10   And p=1-3/10=7/10.   Option: 7/10
