Run a Monte Carlo simulation on this vector representing the countries of the 8 runners in this race:

runners <- c("Jamaica", "Jamaica", "Jamaica", "USA", "Ecuador", "Netherlands", "France", "South Africa")

For each iteration of the Monte Carlo simulation, within a replicate() loop, select 3 runners representing the 3 medalists and check whether they are all from Jamaica. Repeat this simulation 10,000 times. Set the seed to 1 before running the loop.
