Selecting cards at random. In a standard deck of 52 cards, there are 13 spades, 13 hearts, 13 diamonds, and 13 clubs. Carry out a simulation to determine the probability that, when two cards are selected together at random from a standard deck, both have the same suit. Follow the steps given in Example 5 to help set up the simulation.

Do your simulation 10 times and use the result to estimate the probability.
