Question

Events A and B are overlapping.

P(A) = 4/11; P(B) = 3/11, P(A and B) =2/11 .

Find P(A or B).

Answer 1

5/11

Explanation:

Answer 2

5/11

Explanation:

Since the events are overlapping...

P(A or B) = P(A) + P(B) - P(A and B)

P(A) = 4/11

P(B) = 3/11

P(A and B) = 2/11

P(A or B) = 4/11 + 3/11 - 2/11

P(A or B) = 5/11
