Question

Including Jose, there are eight people in his family.
If order matters, how many ways can he arrange his family members into a row of five seats if Jose must sit in the first seat?
O 35
O 840
O 1,680
0 2,620

Answer 1

Answer:

840

Step-by-step explanation:

Since the order matters, we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

In this question:

The first seat is Jose's.

The remaining four are organized among the other 7 members. So

$P_{(7,4)} = \frac{7!}{(7-4)!} = 840$

So the correct answer is:

840
