When there is a finite number of outcomes, each of which is equally likely, we can just count up the possibilities

So let’s take a standard six-sided die (denoted “d6”), which randomly generates a number between 1 and 6, each with an equal chance.

Q: What’s the probability that we get a 1?

A:

Q: What’s the probability that we roll a prime number?

A:

Q: What’s the probability that when we roll 2 d6s and add up the results, we get 7?

A:
