SOLUTION
P (6,3)
- ➝ P(6,3) = n!/(n - r)!
- ➝ p(6,3) = 6!/(6 - 3)!
- ➝ p(6,3) = 6!/(3)!
- ➝ p(6,3) = 6 x 5 x 4 x 3!/3!
- ➝ p(6,3) = 120
Therefore the answer is 120

SOLUTION
P (11,2)
- ➝ 11^P2 = 11!/(11 - 2)!
- ➝ 11^P2 = 11!/9!
- ➝ 11^P = 11 - 10 - 9!/9!
- ➝ 11^P2 = 11 • 10
- ➝ 11^P2 = 110
Therefore, the answer is 110
