Question

six runners are entered in a race.Assume there are no ties In how many ways can first and second place be awarded

Answer 1

P(6,2) = 6!/(6-2)!
P(6,2) = 6!/4! 6! = 1*2*3*4*5*6 4! = 1*2*3*4
P(6,2) = (1*2*3*4*5*6)/(1*2*3*4)
P(6,2) = (5*6)/1
P(6,2) = 30
I hope this makes sense. Let me know if you don't understand any of this. ☺♥
