Step-by-step explanation:

Number of Permutation (P) can be obtained as follow:

nPr = n! / (n– r)!

Number of Combination (C) can be obtained as follow:

nCr = n! / (n– r)! r!

With the above ideas in mind, let us determine the answers to the questions given above.

100. Evaluation of ₅P₄

nPr = n! / (n– r)!

₅P₄ = 5! /(5 – 4)!

₅P₄ = 5! / 1!

₅P₄ = 5 × 4 × 3 × 2 × 1 / 1

₅P₄ = 120

101. Evaluation of ₈C₂

nCr = n! / (n– r)! r!

₈C₂ = 8! / (8 – 2)!2!

₈C₂ = 8! / 6!2!

₈C₂ = 8 × 7 × 6!/ 6! × 2 × 1

₈C₂ = 8 × 7 / 2 × 1

₈C₂ = 56/2

₈C₂ = 28

102. Evaluation of ₇C₀

nCr = n! / (n– r)! r!

₇C₀ = 7! / (7 – 0)!0!

₇C₀ = 7! / 7!0!

Note: 0! = 1

₇C₀ = 7! / 7!

₇C₀ = 1

103. Evaluation 4!

4! = 4 × 3 × 2 × 1

4! = 24
