Variance of a multiplied random variable
In the last exercise you simulated X from a binomial with size 20 and p = .1 and now you'll use this same simulation to explore the variance.

# X is simulated from 100,000 draws of a binomial with size 20 and p = .1
X <- rbinom(100000, 20, .1)
# Estimate the variance of X
# Estimate the variance of 5 * X
