Or if you said what's the probability of getting less than minus 5, well minus 5 was the mean, so half of your result should be above that and half should be below. And if you go to this point right here, you can see that this right here is 50%. So the probability of getting less than minus 5 is exactly 50%. So what you do is, if I wanted to know the probability of getting between negative 1 and 1, what I do is, let me get back to my pen tool, what I do is I figure out what is the probability of getting minus 1 or lower, right? So I figure out this whole area and then I figure out the probability of getting 1 or lower, which is this whole area, well let me do it in a different color, 1 or lower is everything there. And I subtract the yellow area from the magenta area and I'll just get what's ever left over here, right? So what I do is I take, and that's exactly what I did in the spreadsheet.
