A fast food chain claims that all of its quick win soda cups are winners. (There is a little tab you pull off the side of the cup which says either you are a winner or not. Lisa bought 8 sodas to try her luck.

What is the probability that at least 5cups were winners?

What is the probability that between 3 and 6 of the cups 9inclusive) were winners.

What is the probability that at most three cups were winners?

Is reasonable to approximate the distribution using a normal curve? Why or why not?
