Hi

P(8, 3)

= Permutations of 8 objects taken 3 at a time

= 8! / (8 - 3)! .... [Using the formula P(n, r) = n! / (n - r)!]

= 8! / 5!

= 40320/120

= 336

Answer: 336

Please leave a POSITIVE FEEDBACK on my answer so that I get the Credit. BONUS is welcome.

Thanks.

It is thought that prehistoric Indians did not take their best tools, pottery, and household items when they visited higher elevations for their summer camps.

Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a given elevation.
