P (A or B) = 0.65

Step-by-step 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 ...
