Question

How many words, with or without meaning, each of 3 vowels and 2 consonants can be formed from the letters of the word INVOLUTE? is it right write it as 4p3*4p2

Answer 1

Answer:

The number of combinations of 3 vowels and 2 consonants should be 4×6=24  each set of 3 vowels and each set of 2 consonants form a combination, so you need to multiply and not add.

The combinations are ({I,O,E},{N,V}),({I,O,E},{N,L}),…. You can try writing out all 24 combinations as an exercise.

Then you will get 24×120=2880
