Question
If P(A) = 0.3, P(B) = 0.7, and P(A and B) = 0.2, find P(A or B).P(A or B) =
Solution
To find the probability of P(A or B), you can use the formula:
P(A or B) = P(A) + P(B) - P(A and B)
Substituting the given values into the formula, we get:
P(A or B) = 0.3 + 0.7 - 0.2 = 0.8
So, the probability of either event A or event B occurring is 0.8.
