The probability of flu symptoms for a person not receiving any treatment is

0.033.

In a clinical trial of a common drug used to lower cholesterol,

35

of

990

people treated experienced flu symptoms. Assuming the drug has no effect on the likelihood of flu symptoms, estimate the probability that at least

35

people experience flu symptoms. What do these results suggest about flu symptoms as an adverse reaction to the drug?

Assume

44%

of us have Group O blood. A hospital is conducting a blood drive because its supply of Group O blood is low, and it needs at least

230

donors of Group O blood. If

495

volunteers donate blood, estimate the probability that the number with Group O blood is at least

230.

Is the pool of

495

volunteers likely to be sufficient?
