Answer:
Explanation:
The best simulation to compute the probability of it taking at least four shirts to find a blue shirt would be a Monte Carlo simulation. This involves generating random numbers to simulate the selection of shirts and counting the number of simulations where it took four or more shirts to find a blue one. The probability can then be estimated based on the fraction of simulations where the criteria was met. Monte Carlo simulations are useful for problems involving randomness and probability, and they can provide a good estimate of the probability in this situation.
