An orchard owner knows that he'll have to use about 8% of the apples he harvests for cider because they will have bruises or blemishes. He expects a tree to produce about 500 apples. Using the normal approximation to the binomial, find the probability the orchard owner will obtain at most 25 cider apples from the 500.
I think i know where to start: P(x< or equal to 25) but I am completely stuck beyond this point. I have looked at all the other models I have in regards to proportions and square roots of npq and I cannot figure this one out. Any help would be greatly appreciated. Thanks!
