5*4*3*2*1=120 ways
The number of permutations of five things taken five at a time is five factorial, or 120.
5040
5
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
it depends on the shelf of course
7 factorial, or 5,040.
Five numbers can be arranged in 5! = 120 ways.
Five people are to be arranged in a row to have their picture taken. In how many ways can this be done?
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
One row of 5 different brands with each type being represented can be arranged in 5x4x3x2x1= 120 ways
The number of ways that 15 books can be arranged on a shelf is the same as the number of permutations of 15 things taken 15 at a time. This is 15 factorial, or 15!, and is 1,307,674,368,000.
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.
