This is simple for you, hard for me...
I really need to know how to do a question like this for a course I am taking. Can you help?
Out of 2 million hay fever sufferers in Canada, 82% are allergic to ragweed. If a random sample of 7 hay fever sufferers is selected,
a) what is the probability that 3 are allergic to ragweed?
b) What is the probability that 1 is allergic to ragweed?
What is the formula?
