Sarah predicts that 15 percent of all the birds she spots while bird watching will be robins. At the end of the day, she records
that 10 out of the 25 birds she spotted were robins. How does Sarah’s prediction compare with the actual results?
1 answer:
We can turn the probability 10 out of 25 as percentage
×100=40%

Step-by-step explanation:
(a) P = (0.3)(0.2) + (0.5)(0.6) + (0.2)(0.8)
P = 0.52
(b) (0.5)(0.6) = 0.3
P = 0.3 / 0.52
P = 0.58
