Plot a histogram by calling qplot() on the replications.

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

# Existing code for finding the first instance of heads
which(rbinom(100, 1, 0.2) == 1)[1]

# Replicate this 100,000 times using replicate()
replications <- 

# Histogram the replications with qplot
qplot(___)
