What is the probability of rolling a 20 sided dice and having it land on the same number three times in a row?
For bonus points, what is the probability of it hitting a specific pre-determined number each time (for example, 7)

Q1: (1/20)^3 * 20 = 1/400
(Same as explanation for Q2, but multiply by 20 because there are 20 possible numbers to get 3 of)
Q2: (1/20)^3 = 1/8000
(1/20 chance to hit that number for each dice)
