All right, we've got a bag with six red and ten black marbles in there.
00:08
And what we're going to do is we're going to pick one.
00:10
We're going to look at it, record its color, and then put it back in.
00:13
We're going to do that 200 times.
00:15
And at the end of those 200 times, i want to know how many would we expect to have been black.
00:21
All right.
00:21
Well, first of all, let's figure out what is the probability that we pick a black marble.
00:25
So the probability that we pick a black marble out of this bag is going to be the favorable number of marbles.
00:33
10 out of the total number of marbles, that is 16.
00:37
All right, we can reduce that down each are divisible by two, so i can make that a five -eighths probability.
00:43
All right...
