I have a bowl that contains 5 red jelly beans and 3 blue jelly beans only. One by one, every jelly bean is drawn at random and without replacement. What is the probability that the seventh jelly bean drawn is NOT blue?

Please input your answer in the box below, in the format x/y where x and y are relative primes (i.e. if you come up with an answer of 8/10, please input 4/5).
