This says, look, we're looking at a normal distribution. We want to find the cumulative area between two bounds. In this case, it's from negative infinity to zero. From negative infinity to zero, where the mean is eight and the standard deviation is 10. We press enter, and we get approximately 0.212, is approximately 0.212. Or you could say, what is the probability that the woman is taller than the man? Well, 0.212, or approximately, there's a 21.2% chance of that happening, a little better than one in five.
