All right, so for this question, we have a set of colored balls.
00:05
So i wrote them in the colors described by the problem.
00:08
There's 1, 2, 3, 4 in green, 5 through 11s in red, and 12 through 14th in yellow.
00:13
And we're asked several questions about whether certain drawings are independent.
00:20
So the first one is drawing a green ball independent from the event, drawing an even -numbered ball.
00:26
So for this one, i'm going to look for the probability of drawing a drawing.
00:30
An even -numbered ball in the whole population, which is 7 out of 14, and the probability of drawing an even ball out of the green population, which is 2 out of 4.
00:46
Are those the same? yes, so those are independent.
00:52
For the second one, is the event drawing a green ball independent from the event drawing odd number ball? also, yes, for the same reason.
01:00
Odd has 7 out of 4.
01:01
The green odd balls are 2 out of 4, so yes, that's independent...
