Okay, in this one, we are recording the number of times that we roll a die and how many numbers we get for each roll.
00:10
So the first thing we need to do is add up all of our frequencies to find our total.
00:15
Okay, so our total is going to be everything in the frequency column added together.
00:20
So i'm going to use my phone calculator for this.
00:23
That's going to be 12 plus 35, 12 plus 35, and then plus 11 plus 23 plus 7.
00:32
And then plus 12, plus 12.
00:34
So we've rolled 100 times.
00:36
Our total is 100.
00:38
It's going to make this a lot easier.
00:39
So the probability that a 3 is rolled, it's going to be the number of times that we roll a 3 divided by 100.
00:45
So the probability that we roll a 3 is going to be, what was it? how many times that we roll a 3? 11 out of 100...
