You and your friends go to a concert. How many different ways can you sit
Assuming that there are n friends in total, the total number of ways that the friends can sit is given by n factorial (n!). This is because for the first seat, there are n options, for the next seat there are n-1 options, and so on until there is only 1 option left for the last seat. Therefore, the total number of ways to sit is:
n! = 1 x 2 x 3 x ... x n
For example, if there are 5 friends, the total number of ways they can sit is:
5! = 1 x 2 x 3 x 4 x 5 = 120
Therefore, there are 120 different ways that the friends can sit at the concert.
