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?

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?
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.
