Now you are ready to find the answer to the question. The lecture graphic points to a box where the probability will appear. All you have to do is read it and record it. For the height example, the probability that a northern European man's height will fall between 140 and 170 cm is .3747. Black Area .
Probability is represented by the black area under the curve.
Look at the normal distribution on Normal Probability Tool. The black area between 140 and 170 represents a probability of .3747. We have set up a correspondence between area on a picture we can see and the concept of probability. This allows us to picture probability clearly and simply. Click and drag .
