Let A and B be events with P (A) = 0.375; P (B) = 0.5, and. Calculate

Question

0.25


0.5


0.625


0.75

Answer 1

To calculate P(A or B), we use the formula:

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

Since A and B are independent events, P(A and B) = P(A) * P(B)

P(A and B) = 0.375 * 0.5 = 0.1875

Therefore, P(A or B) = 0.375 + 0.5 - 0.1875 = 0.6875

So, the answer is 0.6875.
