The probability for event a is 0.3, the probability for event b is 0.6, and the probability of events a or b is 0.8. why are the events not mutually exclusive? the sum of p(a) and p(b) is less than p(a or b). the product of p(a) and p(b) is less than p(a or b). the product of p(a) and p(b) is not equal to p(a or b). the sum of p(a) and p(b) is not equal to p(a or b).

The sum of P(A) and P(B) is not equal to P(A or B).

Step-by-step explanation:

We have that:

The probability for event A is 0.3, P(A)=0.3

The probability for event B is 0.6  P(B)=0.6 and  

The probability of events A or B is 0.8, P(A or B)=0.9

For mutually exclusive events,

Let us check and see if this is true

......This is not true

Therefore events A and B are not mutually exclusive because the sum of P(A) and P(B) is not equal to P(A or B).
