All right, so our probability, we have the zero, one, two, three, four, or five customers in line.
00:06
The probability of zero is 10, 25 percent, have one, 30 percent, 20 percent, 10 percent, and five percent.
00:16
Let me try to straighten this up a little bit.
00:20
So one, two, three, four, and five.
00:24
So a, find the probability that there is two people in line.
00:29
That is a 30 % chance.
00:32
Don't know why i put a pregnancy there.
00:34
B, the probability that at least one, so x is greater than or equal to one.
00:41
A few ways we could do this.
00:42
We can add up one, the probability of one, the probability of two, the probability of three, the probability of four, and the probability of five...
