Question

Find the probability of P(E or F) if E and F are mutually exclusive, P(E), and P(F)?

Answer 1

The probability of P(E or F), when E and F are mutually exclusive, is equal to the sum of their individual probabilities.

Step-by-step explanation:

To find the probability of P(E or F) when E and F are mutually exclusive, we can use the formula:

P(E or F) = P(E) + P(F)

Since E and F are mutually exclusive, they cannot occur at the same time. This means that the probability of E or F occurring is simply the sum of the probabilities of E and F individually.

For example, if P(E) = 0.3 and P(F) = 0.4, then

P(E or F) = 0.3 + 0.4 = 0.7
