Suppose for events A and B connected to some random experime
Suppose for events A and B connected to some random experiment, P(A)=0.50 and P(B)=0.50. Compute the indicated probability, or explain why there is not enough information to do so.
B. P(AB), with the extra information that A and B are independent.
C. P(AB), with the extra information that A and B are mutually exclusive.
Solution
b)
If A and B are independent.
P(A n B) = P(A) P(B)
Thus,
P(A n B) = 0.5*0.5 = 0.25 [ANSWER]
******************
c)
As they are mutually exclusive, their intersection is impossible,
P(A n B) = 0 [ANSWER]
