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
2 answers:
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.
Answer:
D
Step-by-step explanation:
add all together = 140
make a proportion
59/140=x/300
cross multiply
140x=17700
126.4285
