Room for Leaky Nun and Abcd

1:56 PM

There @LeakyNun ?

@LeakyNun FInd he number of ways of selection of atleast one vowel and one consonant from the word TRIPLE.

Let me explain my method

(IE)(TRPL)

Therfore number of ways = $\dbinom{2}{1}\times \dbinom{4}{1} \times 2^3$

First choose onevowel.

Then one cons.

Then the rest have 2 choices each. - enter the group or not.

Why is this wrong @LeakyNun?

select how many?

@LeakyNun the only constrain is 1 vowel, 1 const should be there.

you can also have 2 vowels 1 const

then 1 vowel 3 const

etc..

exactly

2^4, not 2^3 in the end..

@LeakyNun are you there.

I don’t want to think about it right now
