Diver QUestion (number properties strat guide ch 5 #4

[StephenR114]

I believe the answer is wrong in the book and above to the diver question.

Diver one has a 1/5 chance at a perfect dive (4/5 chance not perfect).

Diver two's chance of a perfect dive is not simply 1/5 because he is dependent on diver one not having a perfect dive (so 4/5 times 1/5 = 4/25).

So Diver threes chance at a perfect dive is 4/5 times 21/25 times 1/5 which equals 84/625. Is there something I'm missing?

do not post the same question more than once.
