00:01
So that means there's six possible rolls.
00:01
And then we're going to toss a coin.
00:03
So that means there's two possible possibilities there.
00:06
So how many elements are going to be in the sample space? we simply multiply that together.
00:11
There's going to be 12 elements in our sample space.
00:14
Now we want to know the probability of we're going to roll a 2, 3, or 4.
00:20
And then we're going to roll, toss a head on the coin.
00:24
So we want to know this probability.
00:26
So we're going to have, what is the probability of a 2, 3, or 4? well, that's going to be 3 rolls out of the 6, and ahead is 1 possibility out of the 2.
00:36
We're simply going to multiply that together.
00:38
That's going to be 1 half times 1 half, which is 1 fourth, which we can put as .25...
