In the game Yahtzee, a player rolls five fair dice and gets a Yahtzee if all five dice show the same number. After the initial roll, the player gets two chances to reroll some of the dice. What is the probability that, on the initial roll, at least four of the dice show the same number? Express your answer as a common fraction.

The probability = [(5  nCr  4 * 5^1) + (5  nCr  5 * 5^0) * 6] / 6^5 = 13 / 648
