So christian, you have that the mean from the investment is normally distributed, and it has a mean of 10 ,000 of profit, and a standard deviation, that's the mean, and the standard deviation is equal to 5 ,000.
00:18
So if we kind of look at this, and it says, find the probability that the investor will not have a net loss, so profit that will not have a net loss so that the value is greater than or equal to zero.
00:37
And so we can see that if this is a normal distribution, we would have 5 ,000 down here at a z value of negative 1, and this is a z value of, excuse me, that zero is the z value of negative 2.
00:54
Or you could convert this to a z value by taking zero minus 10 ,000, and then dividing that by the standard deviation of 5 ,000...
