This problem, we are told that elizabeth gets a bag of cookies and has seven chocolate chip.
00:11
It has nine peanut butter, six sugar cookies, and seven oatmeal cookies.
00:27
And that is, let's see, seven plus nine plus six plus seven.
00:36
That is 16, 22, 29 cookies in total.
00:40
So 29 total cookies.
00:43
Let's just make a note of that.
00:49
And what we want to do is we want to find the probability that elizabeth selects a sugar cookie, eats it, and then selects an oatmeal cookie.
01:00
And we're assuming she is selecting her cookies randomly and not picking them out.
01:07
So first we need to, so, okay, so first sugar.
01:18
We'll write this as probability of sugar and then oatmeal.
01:24
So i'll write it like this, probability of sugar and then oatmeal.
01:28
Well, what's the probability of first picking a sugar cookie? well, there are six sugar cookies in total out of 29 cookies in the bag.
01:37
So it's a six out of 29 chance of getting a sugar cookie...
