Q81.The number of ways of giving 20 distinct oranges to 3 children such that each child gets at least one orange is _____ 1 15
What This Question Tests
This question tests the application of the Principle of Inclusion-Exclusion to determine the number of ways to distribute distinct items among distinct recipients with a minimum quantity constraint.
Concepts Tested
Formulas Used
N = (Total ways) - (Ways where at least one child gets nothing)
N = k^n - C(k,1)(k-1)^n + C(k,2)(k-2)^n - ...
