The probability of two events A and B are0.25 and 0.30 respectively. The probability that both A and B occur is 0.15. The probability that neither A nor B occur is _________	Choose the correct option:
A) 0.45
B) 0.4
C) 0.5
D) 0.05
E) 0.6
we are apply that formula..............   P(AorB)=P(A)+P(B)-P(A AND B)   =.25+.30-.15=
