Question

Given the following information: P(A) = 0.58 P(B) = 0.34 P(A and B) = 0.12 P(B given A) = 0.21

What is the probability of A or B? Round your answer to the nearest hundredth as needed

.P(A or B) =

Answer 1

To find the probability of A or B, use the formula P(A or B) = P(A) + P(B) - P(A and B). Substitute the given values into the formula to find the probability.

Step-by-step explanation:

To find the probability of A or B, we can use the formula:

P(A or B) = P(A) + P(B) - P(A and B)

Given the information provided:

P(A) = 0.58P(B) = 0.34P(A and B) = 0.12

Substitute these values into the formula:

P(A or B) = 0.58 + 0.34 - 0.12 = 0.8

Therefore, the probability of A or B is 0.8 or 80%.
