Question

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?

A. The sum of P(A) and P(B) is less than P(A or B).
B. The product of P(A) and P(B) is less than P(A or B).
C. The product of P(A) and P(B) is not equal to P(A or B).
D. The sum of P(A) and P(B) is not equal to P(A or B).

Answer 2

Answer:

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 less than P(A or B).

Step-by-step explanation:

if A & B are mutually exclusive

then A & B can not happen together

so two event if mutually exclusive

then P(A) + P(B) = P (A or B)

P(A) = 0.3

p(B) = 0.6

P(A) + P(B) = 0.9

P (A or B) = 0.8

0.8 ≠ 0.9

0.8 < 0.9

Hence Events A & B are not mutually exclusive

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 less than P(A or B).
