What is selective distribution?
Selective distribution is a type of retail strategy. It involves making specific items for sale only to specific geographical markets.
One must first consider the number of ordered ways that 4 students may be chosen, and then divide that by the number of ways the four may have been ordered to create a number of distinct groups.
For the orders, there are 30 choices for the first, 29 for the second, 28 for the third, and 27 for the fourth. However, there are a 4 ways within the four to pick the first, 3 ways for the second, 2 for the third, and 1 left for the fourth. The answer may be expressed by the following:
30 x 29 x 28 x 27
______________
1 x 2 x 3 x 4
which evaluates to 27,405 committees.
How do you solve a standard normal distribution?
