A bookstore rents books to students at $2 per book. The cost per hour of running the bookstore is $300. The numbers of books and
the probabilities that the bookstore would rent them in an hour mimics the distribution of the outcomes of flipping four coins. The number of books rented was observed to be the same as the number of heads that appear in a four-coin flip. This distribution is represented in the table..
The question ask for for the probability on how much the value is the book store makes in one hour if the probability of that is the same when you flip four coins. So base on the table you give the possible answer that the bookstore make in an hour is $2. I hope you are satisfied with my answer
