Each morning papa notes the birds feeding on his birdfeeder. So far this month he has seen 59 blue jays, 68 black crows, 12 red robins and 1 cardinal

if 300 birds visit papa's birdfeeder, how many blue jays do we expect to see

A. 140
B. 177
C. 75
D. 126

Sagot :

59+68+12+1=140

Probability of getting blue jays is : 59/140

Therefore, on 300 birds, you would get 126,43 blue jays, but you can’t have a half bird, so 126 is the answer.
