For a single roll of a die, find the probability of getting an even number.
00:00:06.210 --> 00:00:08.610
There are six sides to a die.
00:00:09.820 --> 00:00:19.600
You could land on one or two or three or four or five or six.
00:00:20.370 --> 00:00:26.150
So if we’re finding the probability of getting an even number, let’s find how many even numbers there are.
00:00:27.060 --> 00:00:30.430
Two, four, and six are the even numbers.
00:00:30.460 --> 00:00:39.460
So there are three even numbers out of a total of six numbers.
00:00:40.980 --> 00:00:47.460
So if there are six total numbers and three of those were even, the probability would be three out of six.
00:00:48.070 --> 00:00:49.740
However, we need to reduce.
00:00:49.740 --> 00:00:57.590
And three-sixths reduces to one-half because three and six are both divisible by three.
00:00:57.730 --> 00:01:01.920
Three goes into three once and three goes into six twice.
00:01:02.520 --> 00:01:09.790
So the probability of getting an even number would be one-half, which could also be written as 50 percent.
