Okay, if we throw two dice, there will be a total of 36 outcomes possible, ranging from a low score of two, and we have three, one, two, one, two, one, three, one, two, and so on.
00:27
Five, six, seven.
00:31
Seven is the most frequent, because one, six, one, six, one, six, one, six, one, 25, 5, 2, 3, 4, and 4, 3.
00:43
6 ways to get a 7.
00:46
Here, you will find there are 4 ways, here 5 ways, and then going on 8, 9, 10, 11, 12.
01:03
It goes down again.
01:05
Here is 5 ways, 4 ways, 3 ways, 2 ways, 1 way.
01:10
And the key one here is 10.
01:14
And 10, the three ways, will be 6 plus 4, 4 plus 6 and 5 plus 5.
01:26
If you want to, you can do the entire table.
01:30
But not required here.
01:32

01:40
P of f.
01:41
My sample space is every possible outcome, which will be 36 outcomes...
