There are 8 students in a class. 5 of them are selected to form a committee where each member is assigned a unique position in the committee (President, Vice President, etc.) How many different committees are possible

Step-by-step explanation:

This is a classic permutation problem. We are given the number of permutations of 8 things taken 5 at a  time

And we have the formula:

P(n, r) = n!/(n - r)!

P(8, 5) = 8!/(8 - 5)!  

= 8x7x6x5x4x3x2x1 / 3x2x1

= 6720  

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
