Plese use R-Studio to answer this question.

qbinom(p, size, prob) gives the smallest x value so that the probability of being less than or equal to x is at least p. Try the following: pbinom(0:10, size=10, prob=0.5) ; qbinom(0.75, size=10, prob=0.5) What is the value for which 90 percent of the probability is smaller than it, when you flip a fair coin 20 times?

Answer 1

Here, size = 20 , p=0.9 , prob = 0.5

The value for which 90 percent of the probability is smaller than it, when you flip a fair coin 20 times is 13.
