Fifteen athletes compete in the triple-jump event at a grand prix meeting. the distances (d cm) that they jump are normally distributed according to d=N(17.1,0.04).
In the first half of the competition, the athletes have to jump a distance of 17.15m to qualify for the final section. How many athletes would you expect, the nearest whole number, to achieve this?

Each person qualifying is an independent event with the same probability. What distribution does that suggest? And what's its expectation?
