In how many ways a jeweler can arrange a continuous bracelet consist of 10 distinct gemstones in such a way that the ruby, sapphire, and emerald should be next to each other?

Sagot :

n= 10-3+1= 8

Minus 3 dahil iilan ba ang given? 3 right. (Ruby, sapphire and emerald) then always add 1.

P=(8!)(3!)

P= (40, 320) (6)

P= 241, 920 ways
