Question 143281: Charmayne is organizing a track meet. There are 4 runners in her class. Each runner must compete one-on-one against each of the other runners in her class.
How many races must Charmayne schedule? This would be 4*3*2*1=24 (Is this correct?)
Must Charmayne schedule permutations or combinations? Permutations (Is this correct?)
Thanks
