i need help with parts d and e

Suppose A and B are events such that P(A) = 0.4, P(B) = 0.5 and P(A and B) = 0.2. Calculate the following: a) P(A or B) = [A] b) P(A given B) = [B] 4 C ) P(B given A) = [C] d) P(Ac) = [D] = 1.75 e) P(BC) = [E] f) Are A and B mutually exclusive? Just answer yes or no,[F] O g) Are A and B independent? Just answer yes or no. [G]
