Question

The probability that at least one of A and B occur in 0.67. If A and B occur simultaneously with probability 0.15, then find P(A) + P(B)

Answer 1

Step-by-step explanation:

p(AUB)=0.67

p(A intersection B)=0.15

p(AUB)=p(A)+p(B)-p(A intersection B)

0.67. =p(A)+P(B)-0.15

0.67+0.15=p(A)+p(B)

p(A)+p(B)=0.82
