Hello and welcome.
00:02
The probability of two events happening, at least one of the two events happening, is the probability of event one plus the probability of event two.
00:10
So since we're rolling two dice, each of which has six potential values, the total number of combinations is one over, is six times six, which is 36.
00:21
So let's actually just write them all out.
00:23
So dice one is going to be written as a black number, so like this.
00:27
And then the dice two will be like this.
00:42
So it's just easier for you to differentiate the dice from one another.
00:51
And we're almost done.
00:59
Last one.
01:03
Okay.
01:04
So now we want to keep only the ones that add up to 8 or 11.
01:14
For example, 1 and 1 does not add up to 11 or 8.
01:20
So if you look at this entire first row over here, none of these add up to 8.
01:28
For example, 1 in 1 and 1 doesn't add up to 8.
01:30
1 in 2 doesn't add up to 8...
