Answer:
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 ....
