Researchers are interested in finding out how likely it is that third graders have pizza for lunch. They represent this as P(P) or the probability of having pizza. Based on observations of a few third graders in the lunch line, they assess P(P) as 0.75. More convincing evidence that P(P) is .75 would be:

a. Out of 500 randomly selected third grade students, 375 had pizza.
b. Out of 20 randomly selected third grade students, 15 had pizza.
c. Out of 10 randomly selected third grade students, 7.5 had pizza.
d. Out of 500 randomly selected third grade students, 75 had pizza.
