We have a lottery where there's nine possible, or there's actually 10 possible digits, 10 possible numbers, because we have the digits one through nine, and then we also have zero.
00:18
There's 10 possible numbers, and we have the counts of the different outcomes.
00:23
So first of all, let's use this to think about the experimental probability of an even number.
00:27
So that means from our data, from our experiment, if we were to pick one of our random trials, what would be the chance that we get an even number? so notice there's 500 trials.
00:40
And so the number of times we have an even was the number of times of zero, which was 61 plus two, which was 54, plus four, which was 40, plus six, which is 48, plus eight, which is 46.
00:56
So we had the number of evens, and then we divide that by the total, which is 500.
01:03
So this is 249 over 500.
01:10
So that's very close to one half.
01:12
It's 0 .498, 0 .498...
