In this problem, it is said that two four -sided dice are rolled and we keep track of the total of the two dice.
00:07
And first of all, we need to draw a 4 by 4 grid that demonstrates the different results for the total of the two dice.
00:15
So let's draw our grid.
00:18
So consider the outcomes on the first die, we can get a 1 or a 2 or a 3 or a 4.
00:24
And consider the outcomes we can get on the second die.
00:27
It will be a 1 or a 2 or a 3 or a 4.
00:30
And this is because the dice are four -sided.
00:34
So we're going to now form a grid, which gives us the total.
00:41
So what do we have over here? that will be the total when we roll two dice and we get a 1 on both dice.
00:48
So we have 1 plus 1 and that is 2.
00:50
So we're just going to write a 2 over here.
00:53
Now consider this spot.
00:55
So we have a 2 on the first die and a 1 on the second die.
00:58
So what is the total? that's 2 plus 1.
00:59
That's 3.
01:01
And for the next one, we will have 3 plus 1.
01:04
That is 4.
01:05
So we write that down over here...
