Assume A and B are independent events with P(A)= 0.2 and P(B)= 0.3.
let C be the event that none of the events A and B occurs, let D be
the event that exactly one of the events A and B occurs. Find P(A
given D)?

Given two events A and B such that P(A) =0.2, P(B)=0.3, P(A⋃B) =
0.44. Are A and B disjoint? Are they independent? Why? Find
P(A|B).

For 2 independent exclusive events A and B, P(A) = 0.2 and P(not
B) = 0.7. 1) What is P(A and B) ?
2) What is P(A or B) ? Assume just for this question that P(A
and B) = 0. 3) What is P(not A and B) ?
4) What is P(A and not B) ?
5) What is P(not A and not B) ?
