caught either a blue or red fish, then what percentage of whale fishes were successful in
catching at least one blue fish and at least one red fish?
Answers
Given : 80% of the whale fish caught a blue fish at least once, and 60% caught a red fish at least once
10% of the whale fish never caught either a blue or red fish,
To Find : percentage of whale fishes were successful in catching at least one blue fish and at least one red fish
Solution:
Caught Blue Fish = 80%
caught a red fish = 60 %
whale fish never caught either a blue or red fish, = 10 %
Caught Both fish = x
=> 100 = 80 + 60 - x + 10
=> x = 50 %
50 % whale fishes were successful in catching at least one blue fish and at least one red fish
