Best ResponseYou've already chosen the best response.1Two events A and B are mutually exclusive this implies that if A occurs B can't occur and if B occurs A can't occur. So here P( A intersection B)=0 (intersection or simultaneous occurrence or and) We know that \[ P(A\ or\ B)= P(A)+P(B) P( A\ and\ B)= 0.25+0.350=0.60\]
