Question

P(A) = 0.60, P(B) = 0.20, and P(A and B) = 0.15. What is P(A or B)?

Answer 1

0.65 ~apex

Explanation:

Answer 2

P(A or B) = 0.65

Explanation:

Given that P(A) = 0.60, P(B) = 0.20, and P(A and B) = 0.15

We have to find P(A or B)

Apply the formula:

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

Now substitute the values in the formula:

P(A or B) = 0.60 + 0.20 - 0.15

P(A or B) = 0.80 - 0.15

P(A or B) = 0.65

Thus P(A or B) = 0.65 ....
