20. Consider a small city in Central Asia (population: 120) where everyone's favorite color is either red or purple. Thirty of these people's favorite color is red.

If 13 people are selected at random and with replacement, which of the following lines of R code computes the probability that 7 of them have favorite color red?

A. pbinom(7, n=13, prob=0.25)

B. pnorm(7, mu=13, sigma=0.25, lower.tail=FALSE)

C. pnorm(7, mu=13, sigma=0.25)

D. dnorm(7, mu=13, sigma=0.25)

E. dbinom(7, n=13, prob=0.25)

F. pbinom(7, n=13, prob=0.25, lower.tail=FALSE)
