A heating and cooling company advertises that any customer buying an air conditioner during the first 16 days of July will receive a 25 percent discount if the average high temperature for this 16-day period is more than five degrees above normal.

If we select 10 customers that purchased an air conditioner during the first 16 days of July, what is the probability that exactly eight of them (not more and not fewer) will have received the discount?
