Given that P(X) = 0.5, P(Y) = 0.45, and P(X|Y) = 0.3 which one of the following is the value of P(X and Y)?
A: 0.135 E: 0.15
B: 1.25 F: 0.8
C: 0.225 G: 0.85
D: 0.65 H: 0.95
Ok, assuming that it's an inderpendant event I think the answer is C
p(X) * p(Y) = P(X and Y)
0.5*0.45=0.225
but the booklet says the answer is A - what am I missing?
