god i hope you get another * for that, if people here have to put up with the crap from your math homework we at least get to make fun of you while we do it.

I have a more elegant solution, and a slightly different answer.

The problem is binomial because it is either effective or not so we can use the binomial probability density function. If you have a Ti83 it will work.

binompdf(n,p,k)
n = sample space
p = probability of success (we determine success as a defective hair dryer)
k = exact number of successes we are looking for

binompdf(10000,.02,225) = .0058

edit*** the reason for our different answers is that mine is exact and you used the normal approximation for a binomial distribution by taking off the .5's
