In a maine town there 55% red sox fans. If the population is 34,500, what is the probability that in a sample of 25 chosen at random there will be 10 red sox fans?
Answer provided by our tutors
total fans = 34500
red sox fans = 55% of 34500 = 18,975
other fans = 15525
probability that 10 out of 25 are red sox fan = (18975C10 *15525C15) /34500C25
