For a certain insured, the probability of making no claim during a policy period is 0.60. The probability of making only 1 claim is 0.25. What is the probability that this insured makes more than 1 claim during the policy period?
Explanation:
The probability of "more than 1 claim" is the complement of "no more than 1 claim" (which means 0 or 1 claim).
Given:
First, calculate the probability of no more than 1 claim: P(0 or 1 claim) = P(0 claims) + P(1 claim) = 0.60 + 0.25 = 0.85
Then, the probability of more than 1 claim is the complement: P(more than 1 claim) = 1 - P(0 or 1 claim) = 1 - 0.85 = 0.15
Therefore, the correct answer is A. 0.15.
