So given this, can you think about how to tackle this question? The probability that the woman is taller than the man. All right, now let's work through this together and to help us visualize, I'll draw the normal distribution curves for these three random variables. So this first one is for the variable m. And so right here in the middle, that is the mean of m. And we know that this is going to be equal to 178 centimeters. We'll assume everything is in centimeters. We also know that it has a standard deviation of eight centimeters. So for example, if this is one standard deviation above, this is one standard deviation below, this point right over here would be eight centimeters more than 178, so that would be 186.
