Answer:
5040
Step-by-step explanation:
By the law of permutation
Total ways are = nPr = n!/(n-r)!
= 10!/(10-4)!
=10*9*8*7
=5040
Another approach,
We have total four empty slots to be filed and number of choices 10
In next turn three empty slots and 9 choices left
So on We would have all slots filled by
10*9*8*7 choices
=5040 ways
