The demand for a product is estimated to be normally distributed with u=200 and o=40. Let x be the number of units demanded and find the following probabilities.
a. P(180< x <220)
b. P(x > 250)
c. P(x < 100)
d. P(225 < x < 250)
As x follows a normal distribution with u=200 and o=40. Let Z=(x-200)/40. Then Z follows the standard normal distribution N(0,1).
Probability and demand for a product are investigated.
