All right, number 10, we have these little sets.
00:04
We have a is 1, 3, and 4.
00:07
B is any number such that x is an even whole number less than 9.
00:13
C is 2, 5, 7, and 10.
00:16
D is x such that x is an odd whole number less than 10.
00:21
And we want a union b.
00:24
Well, just because my little mind sometimes get confused, i want to do an even number and i want to do less than 10 because that's kind of easy for me to list, which is 0, 2, 4, 6, and 8.
00:39
So in this instance, it's going to be easier for me to do that than remember and think through it every time.
00:46
So this time we want an odd number that is less than 10, which would be 1, 3, 5, 7, and 7...
