Problem

Each student in a class travels to school either by bus, by bicycle, or on foot. The probability that a student comes by bus is 0.40, while the probability that a student walks is 0.25. If these three modes cover all possibilities and no two modes overlap, calculate the probability that a student comes by bicycle.
