In the game of Yahtzee, you place 5 fair dice in a cup, shake them up, then roll them. If they all display the same number then
you have rolled a "Yahtzee" and get 50 points. One example of a Yahtzee is to roll: 1, 1, 1, 1, 1. Another is to roll 6, 6, 6, 6, 6.
What is more likely? To get a Yahtzee by rolling all Is or to get a Yahtzee by rolling all 6s?

1) It is more likely to roll all Is than it is to roll all 6s.
2) It is more likely to roll all 6s if the dice are white.
3) Both types of Yahtzee are equally likely.
4) It is more likely to roll all 6s than it is to roll all Is.
5) It is more likely to roll all Is if the dice are red.
