I have the following task: The country has the same number of men and women. Normal height distributions for each sex are shown in the picture . The height of an individual person is 170 cm. Find the probability that this person is a woman.
I have an idea to simply write the normal distribution formulas for men and women, substituting the height 170 for x, and then find the desired probability as the ratio of the distribution value from 170 for men and the value of the sum of the distributions for men and women (also for x = 170). But I doubt the correctness of this approach a little, since it turns out that we divide the distributions by each other, and in the end we should get the probability
