Question

Accessibility Text Size Aa Aa Aa Type your answers into the boxes. A fish bowl contains blue, green and red plastic fish. When a fish is picked out at random, the probability of it being blue is 0.7 and the probability of it being green is 0.2. A prize is given if a red fish is picked out. What is the probability of Matt picking a red fish? (Give your answer as a decimal.) There are 60 fish in the fish bowl. How many of the fish are red?

Answer 1

Answer:

Step-by-step explanation:

Since the fish bowl contains blue, green and red plastic fishes, it means that a fish picked at random would be any of these colors.

the probability of it being blue is 0.7 and the probability of it being green is 0.2, then probability of Matt picking a red fish is

1 - (0.7 + 0.2) = 0.1

If there are 60 fishes in the fish bowl, then the number of fishes that are red is

0.1 × 60 = 6 fishes
