How many six digit numbers can be formed if no digits can be repeated?

Since no digits can be repeated, we will use the formula for permutations.

In this case, the number of the total objects (n) is the same value of the number of objects to be chosen (r).

In the formula P (n,r), if n = r, then P (n,r) = n!

P (n,r) = n!

P (6,6) = 6!

P (6,6) = 6 • 5 • 4 • 3 • 2 • 1

P (6,6) = 720 six digit numbers
