The area under the standard normal curve (bell curve) represents probabilities. The curve is more densely populated closer to the mean (z = 0). Therefore, the area between z = 0.0 and z = 1.25, which is closer to the mean, is larger than the area between z = 1.25 and z = 2.5, which is further away from the mean.
