At a benefit concert, nine bands have volunteered to perform but there is only enough time for six of the bands to play. How ma
ny lineups are possible?
1 answer:
You have to calculate how many ways you can select six things (r)
from a set of 9 things (n). (See attached formula).
9! / 6! * (3!) =
9*8*7 * 6! / 6! * 3! =
9*8*7 / 3! =
3 * 4 * 7 = 84 lineups
