Jim's fishbowl contains 5 tetras, 3 goldfish, and x platies. He removes one fish from the fishbowl at random. If the probability of removing a goldfish from the bowl is 1 out of 3, how many fish does Jim have?

Answer 1

The probability of removing a goldfish from the bowl is 1 out of 3, which means that there are 3 goldfish in the bowl. This means that x = 3, since Jim's bowl contains only tetras, goldfish, and platies.

Jim has 5 tetras, 3 goldfish, and 3 platies, for a total of 5 + 3 + 3 = <<5+3+3=11>>11 fish. Answer: \boxed{11}.
