Compute the permutation.
Anon25 [30]
So you have 8 digits (number available) to form 3 digit numbers (number selected).

Using the formula ^{a} P_{c} where a is the number of available digits, P is the permutation function and c is the number of digits to be selected.

The number of three digit numbers that can be formed = ^{8} P_{3}
                                                                                       = 336

                                                <span> O R

</span>By using the formula Permutation =  \frac{a ! }{( a - c) !} where a is the number of available digits and c is the number of digits to be selected.<span>

</span>⇒  Permutation = \frac{8 ! }{( 8 - 3) !}
<span>
</span>⇒  Permutation = \frac{40, 320 }{120}
<span>
</span>⇒ Permutation = 336<span>
