The number of permutations of five things taken five at a time is five factorial, or 120.
One row of 5 different brands with each type being represented can be arranged in 5x4x3x2x1= 120 ways
5! = 120
120. You do 5*4*3*2*1=120. you multiply the number that you are given for example how many times can books 3 be arranged on a shelf you multiply 3*2*1=6 that is your answer
Top shelf has one plant, second shelf has three plants, third shelf has five plants, fourth shelf has seven plants and the bottom shelf has nine plants. 1+3+5+7+9=25
They typically have a shelf life of four to five years.
Five numbers can be arranged in 5! = 120 ways.
The shelf life of sterile saline solution is 60 months. This is the equivalent of about five years. It has a long shelf life.
Theorem: A number of permutation (the possible arrangements) of n distinct objects is n!Answer: There are 5! = 5 x 4 x 3 x 2 x 1 = 120 ways in which the five cereal boxes can be arranged in a shelf.
Five people are to be arranged in a row to have their picture taken. In how many ways can this be done?
