All right, this problem, we are tossing and dye.
00:04
If a four appears, a ball is drawn from earn 1.
00:07
So let's draw a tree for this.
00:09
Probability of a four is one -sixth.
00:13
Probability of not a four is five, six.
00:15
So we're making a tree out of this.
00:18
Now, they're in earn 1, we have two red, four white, and six black balls.
00:24
What that means is that the probability of drawing a red is two out of 12.
00:29
So here in earn 1, the probability of drawing a red is two out of 12.
00:35
Now in earn 2, we have 1 red and 5 black balls.
00:39
Probably right over here is 1 out of 6...
