For a single roll of a die, find the probability of getting an even number.

There are six sides to a die. You could land on one or two or three or four or five or six.

So if we’re finding the probability of getting an even number, let’s find how many even numbers there are. Two, four, and six are the even numbers. So there are three even numbers out of a total of six numbers.

So if there are six total numbers and three of those were even, the probability would be three out of six. However, we need to reduce. And three-sixths reduces to one-half because three and six are both divisible by three. Three goes into three once and three goes into six twice. So the probability of getting an even number would be one-half, which could also be written as 50 percent.
