The probability of two events A and B are0.25 and 0.40 respectively. The probability that both A and B occur is 0.15. The probability that neither A nor B occur is _________	Pick:
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+.40-.15=

<output>0.5</output>
.50   but the probability of neither A nor B=1-.50= 
<gadget id="calculator">1-.50</gadget>
<output>0.5</output>
0.50   ANSWER:0.5
