So - If P(A) = 3 and P(B)= 0.5, and P(A u B) = 0.6, then what is the probability of A given B?
The answer is 0.4000 --.

CDM,
Okay, here's what I get...
----------------
P(A) = 0.3
P(B) = 0.5
P(A u B) = 0.6
P(A/B) = 0.4
----------------
P(A/B) = P(B/A) * P(A) / P(B)
P(A/B) = 0.666666666666667 * 0.3 / 0.5 =
0.4
Hope that helps,
