You are feeling kind of crazy, so you are going to have the owner of the pet store randomly pick a fish for your aquarium at home.

a. A tank at the pet store contains 9 spotted guppies, 14 red barbs, 10 red tetras, and 7 golden platys. What is the probability (expressed as a percent) of getting a red-colored fish from this tank?

b. In a different tank that contains only golden platys, the probability of getting a female fish is 30%. If there are 18 female fish in the tank, how many total fish are in the tank?
