Question

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.

Answer 1

Answer:

Explanation:

# Run Monte Carlo 10k

B <- 10000

results <- replicate(B, {

 winners <- sample(runners, 3)

 (winners[1] %in% "Jamaica" & winners[2] %in% "Jamaica" & winners[3] %in% "Jamaica")

})

mean(results)
