Calculate the number of different ways the 22 students can sit down in the 80 available spaces of a classroom.
Homework Answers
Solution:
Here we will use permutation because permutation is the several
possible ways in which a set of number of things can be arranged or
ordered.
So there are total no. of student = 22
Total available spaces = 80
So total number of different ways = 80P22 = (80!)/(80-22)! =
80!/58! = 30447815206422600000000000000000000000000 or
3.04478152?+40

In how many ways may n people sit around a round table? (Assume that when people are sitting around a round table, all that really matters is who is to each person’s right. For example, if we can get one arrangement of people around the table from another by having everyone get up and move to the right one place and sit back down, then we get an equivalent arrangement of people. Notice that you can get a list from...
