At a major and minor street intersection, one finds that, out of every 100 gaps on the major street, 65 are acceptable, that is, large enough for a car arriving on the minor street to cross. When a vehicle arrives on the minor street:
(a) What is the probability that the first gap is not an acceptable one?
(b) What is the probability that the first two gaps are both unacceptable?
(c) The first car has crossed the intersection. What is the probability that the second will be able to cross at the very next gap?
