Answer 1

The number of ways to arrange 4 cats out of 7 can be found using the formula for permutations:

P(7,4) = 7! / (7-4)!

P(7,4) = (7 x 6 x 5 x 4 x 3 x 2 x 1) / (3 x 2 x 1)

P(7,4) = 7 x 6 x 5 x 4

P(7,4) = 840

Therefore, there are 840 different ways to arrange 4 cats out of 7 in a single-file line.
