Question

in a fish tank, there are 24 goldfish,2 angel fish, and 5 gopppies. if a fish is selected at random, find the probability that it is the goldfish or an angel fish?

Answer 1

There is a total of 31 marine lives in the fish tank. The probability of picking a goldfish is 24/31 since there are 24 goldfish. Further, the probability of picking an angel fish is 2/31 as there are 2 angel fish in the tank. The final probability is the sum of the two probabilities,
P = (24/31 + 2/31) = 26/31
The answer is 26/31.
