Question: Explain why the statement is incorrect. Joanne, a high school senior, has applied for admission to four colleges, A, B, C, and D. She has estimated that the probability that she will be accepted for admission by A, B, C, and D is .5, .3, .1, and .08, respectively. Thus, the probability that she will be accepted for admission by at least one college is P(A) + P(B) + P(C) + P(D) = .5 + .3 + .1 + .08 = .98.
