Okay, so this problem gives us a game that's played with the dominoes in the picture.
00:05
It says what's the probability of the total number of dots on the domino being three or less? so for the blank dominoes, there's only four.
00:16
For the single, so we can write this down.
00:19
So it's going to be four for the blanks.
00:23
And this is all going to be over 28 because there's 28 total dominoes.
00:27
For the single pip, we're going to have one, two.
00:34
For the two pip dice, we won't have any, and further on, none of them will equal three.
00:45
Okay, so we only have four plus two plus zero, which is equal to six over 28, which is a three out of 14, probability that you get a domino with three or less.
01:01
Okay, part b is greater than three.
01:07
So that's just the complement of the previous one.
01:11
So the complement of 3 .14th is going to be 11 .14th.
01:17
Okay.
01:18
C does not have a blank half...
