Question

Suppose the newspaper states that the probability of rain today is 25%. What is the probability of the complement? (Enter your answer to two decimal places.) Enter a number.​

Answer 1

The probability of the complement (no rain) is 0.75 or 75%.

Explanation:

The complement of an event A is the probability of A not occurring, which is equal to 1 - P(A).

Given that the probability of rain today is 25%, the probability of no rain (the complement of rain) is:

P(no rain) = 1 - P(rain)

P(no rain) = 1 - 0.25

P(no rain) = 0.75

Therefore, the probability of the complement (no rain) is 0.75 or 75%.
