Number of possible outcomes when a die is thrown once is 6 (1, 2, 3, 4, 5, and 6). Now, to get a perfect square as an outcome, two outcomes are possible (1, 4) in one throw of a die. To not get a perfect square as an outcome, 4 outcomes are possible (2, 3, 5, 6) in one throw of a die.

## What is the probability of rolling two 4s?

Probability of rolling a certain number or less with one die

---|---|

2 | 2/6 (33.333%) |

3 | 3/6 (50.000%) |

4 | 4/6 (66.667%) |

## What is the probability of rolling the same number on 4 dice?

The probability that 4 dice show the same number is **(1/n) ^4**, where n equals the number of sides on a given die.

## What is the probability of rolling at least two 3’s?

Of those, only two combinations add to 3: 1|2 and 2|1. So the odds of rolling a 3 on any throw are 2/36 or 1/18, or **about 5.56%**.

## What is the probability of rolling a 6 four times in a row?

Expert Answers

When rolled 4 times, each time has a probability of **1/6**.

## What is the probability of rolling at least 2 double sixes?

The Monty. Hall Problem

There are 6 ways we can roll doubles out of a possible 36 rolls (6 x 6), for a probability of 6/36, or 1/6, on any roll of two fair dice. So you have a **16.7%** probability of rolling doubles with 2 fair six-sided dice.
