Write the number of permutations in factorial form. Then simplify.
How many different ways can you and five friends sit in your assigned seats when you go to a concert?
A. 6!; 120
B. 6!; 720
C. 5!; 120
D. 5!; 30
B. 6!; 720
The number of permutations in factorial form for this problem would be 6!.
To simplify 6!, we calculate it as follows:
6! = 6 x 5 x 4 x 3 x 2 x 1 = 720.
Therefore, the correct answer is:
B. 6!; 720
