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
