Question 350742: This past summer the LifeSaving Society did a survey about who was at risk in the water, with the goal of reducing swimming accidents. (Globe and Mail July 15 2010)
Consider a similar study done that shows that 96 % of those born in Canada can swim but only 83 % of new Canadians can swim. In a random group of 12 new Canadians, find the probability that exactly 8 can swim.

You can put this solution on YOUR website! Consider a similar study done that shows that 96 % of those born in Canada can swim but only 83 % of new Canadians can swim. In a random group of 12 new Canadians, find the probability that exactly 8 can swim.
-----
Binomial Problem with n = 12 and p = 0.83
P(x = 8) = 12C8*0.83^8*0.17^3 = binoompdf(12,0.86,8) = 0.0569
