Question

What is the probability of rolling a 4, 5, and 6, in that order, on three rolls of a single six-sided die

Answer 1

1:216

Explanation:

The probability of getting a 4 would be 1/6. The probability of getting a 5 would be 1/6 and the probability of getting a 6 would be 1/6. The bottom number is the total number of outcomes (1,2,3,4,5,6) and the top number is out of that set, how many do I want. In the case of wanting a 4, I want 1 out of those 6 numbers and so on.

Now we multiple these together 1/6 x 1/6 x 1/6 and get 1/216 or another way to write this is 1:216
