The value of the probability P(A u B') is 0.8218

How to determine the probability?

The given parameters are

P(A) = 0.67

P(B) = 0.54

P(A u B) = 0.89

From the above parameters, we have

P(B') = 1 - P(B)

P(B') = 1 - 0.54

P(B') = 0.46

So, we have

P(A u B') = P(A) + P(B') - [P(A) * P(B')]

This gives

P(A u B') = 0.67 + 0.46 - (0.67 * 0.46)

Evaluate

P(A u B') = 0.8218

Hence, the value of the probability P(A u B') is 0.8218
