Question

Ech morning papa notes the brids feedings on his birdfeeder. So far this month he has seen 59 blue jays 68 black crows and 12 red robins and 1 cardinal. If 300 birds visit papa's birdfeeder, how many blue jays can we expect to see

Answer 1

126

Explanation:

Total number of birds already observed: 59 + 68 + 12 + 1 = 140

Number of blue jays observed: 59

Fraction of blue jays: 59/140

Number of blue jays expected in 300 birds:

59/140 * 300 = 126

Answer: 126
