Question

In a population of 300 pigeons, 55% are female. If 40% of the male pigeons are not white, how many male pigeons are white? 135 180 81

Answer 1

81

Explanation:

Assuming the pigeons are either male or female, the 45% of them that are not female are male. Of those, there are 40% that are not white, so 60% are white. Then the number of white male pigeons is ...

60% of 45% of 300 = 0.60 · 0.45 · 300 = 81
