There are eight different kittens at a store. I have three different children - how many ways are there to give each child a different kitten?
first child may get one kitten from any eight kitten in 8 ways.
Second child have a choice from rest seven kitten ( one is already booked for first child) in 7 ways.
Third child may choose one from remaining six kitten in 6 ways.
Total numbers of ways such each child get one different kitten is 8*7*6=336 ways
