Out of 6 consonants and 4 vowels, how many words each containing 3 consonants and 2 vowels can be formed?

Answer 1

no. of ways in which 4 consonants can be choosen=6C3=120

no. of ways in which 2 vowels can be choosen from 4= 4C2=12

now,total no. of words that can be formed=6C3×4C2×5factorial

5factorial because the words contain 5 letters,which can also be arranged among each other

so,

total no. of words=12×120×120

=>14400×12=172800

hence total no. of words which can be formed will be 172800
