Question

If P(A)=0.6, P(B)=0.3, and P(A and B)=0.18, find P(A or B).

Answer 1

Answer:

The value of P(AUB) = 0.72

Step-by-step explanation:

As

• P(A) = 0.6

• P(B) = 0.3

• P(A∩B) = 0.18

We can determine the value of P(A∩B) Using the formula

P(AUB) = P(A) + P(B) - P(A∩B)

            = 0.6 + 0.3 - 0.18

             = 0.72

Therefore, the value of P(AUB) = 0.72
