Question

1.Jumlah hasil dari permutasi p(4,4)
2.Nilai permutasi p(10,3)

Answer 1

Langsung aja yy

1.
P = n! / n1! n2!
P = 8! / 4! 4!
P = 8×7×6×5×4! / 4×3×2×1 4!
P = 1680 / 24
P = 70

2.
P = n! / n1! n2!
P = 13! / 10! 3!
P = 13×12×11×10! / 10! 3×2×1
P = 1716 / 6
P = 286.

semoga berguna +_+

tanya aja kalo kamu gak ngerti y ^_^

Answer 2

Rumus permutasi P(a,b) maka P= a!/(a-b)! dengan a<=b
1. P(4,4) = 4!/(4-4)!
=(4x3x2x1)/0!
= 24/1
= 24

2. P(10,3)= 10!/(10-3)!
= 10!/7!
= (10x9x8)x7!)/7!
= 10x9x8
= 720
