So first thing, let's set up a tree diagram.
00:02
So suppose i roll two dye, one red, one green.
00:05
And they all have six possibilities.
00:06
So my possibilities for my red dye are 1, 2, 3, 4, 5, 6.
00:10
And then if i roll a green, for example, i could roll a 1, 2, 3, 4, 5, and 6 for my green dye.
00:19
I can roll 2, 3, 4, 5, and 6 from my red dye.
00:26
And i could do this for each of my numbers.
00:29
So 4 in 1, 4 in 2, 4 to 3, 4 in 4 and 4 and 5, 4 and 6, and so on and so forth, i'm right now in the room, so i'm going to write these down here.
00:39
So then how many total possibilities are there? well, what i can do is i can count the different roots that i have, or what i could do is i could just say, okay, there's six possibilities of red, 6 for a green.
00:56
So six times six or a total of 36 total outcomes that i could have.
01:04
Assume they're fairly rolled.
01:06
What's probably that the sum is 10? okay.
01:09
So what are two options where the sum will be 10? well, i know that i could have.
01:15
Can i have a 1 and a 6? no, a 2 in a 6 is 8...
