Question

Given P(A) 0.3, P(B) = 0.43 and P(ANB) = 0.249, find the value of
P(AUB), rounding to the nearest thousandth, if necessary.

Answer 1

Answer:

0.481

Step-by-step explanation:

P(A U B) = P(A) + P(B) - P(A∩B)

              = 0.3 + 0.43 - 0.249

              = 0.73 - 0.249

              = 0.481
