Respuesta :
Allison, Buck, Chantal, and Dough compete in a 40 yard dash.
Total number of competitors = 4
First place :
As for the 1st place, any 4 can be get so,
there are 4 ways to get the first position
Since when 1 get the position for the first place
then we are left with 4 - 1 = 3 competitors
Now for the second place :
Number of competitors we have are 3, so any three of them can get this position
There are 3 ways to get second place
Now for the third place:
Number of competitors left = 4 - 2 = 2 competitors
for the third place any two of them can get the third position
There are 2 ways to get the third pace
Now for the fourth place
As we are now left with only one competitor
So, the remaining one get the fourth place
So, number of ways to get the fourth place is 1
Number of ways the 4 competitors finish in 1st, 2nd, 3rd, And 4th place = The product of number of ways get 1st, 2nd, 3rd, And 4th place
Number of ways the 4 competitors finish in 1st, 2nd, 3rd, And 4th place = 4 x 3 x 2 x 1
Number of ways the 4 competitors finish in 1st, 2nd, 3rd, And 4th place = 24
There are 24 ways for the 4 competitors finish in 1st, 2nd, 3rd, And 4th place
Answer : D) 24 ways
