My god, thanks so much for this. Not a single soul has mentioned to me before that the sub-string has to be considered a new letter.

This guy is great! I actually understood & kind of enjoyed this!! 🤯 It was kind of funny because I got lost a little bit & he just so happened to recap right before going into the answer, brought me back on track!! Many, MANY thanks!!!

I was about to juss quit but like you made me get it! thank u 🥺🥺🥺

There combination doesn't matter we removed all the times vowels were together from total ways so remaining is when they are not together

Thank U Sir..

Why you didn’t cancel 4! And 2! In the question abt “mathematics” and vowels that always come together?

Sir you are amazing 😊

Uhm does permutations mean like a group of numbers 1 3 2 if we want to find the most possible outcomes of this group do can we repeat it such as 1 2 3 and 2 3 1 etc.Thanks.

i liked and watched the video !!

I watched and liked it

Bibi Tibi as the condition says all the vowels must be together, all 4 vowels must be considered as 1 unit as they can not be separated. On other word for each combination all the vowels are considered “1letter”. As there is no other condition remaining 7 letters are all’ considered separately. Let me know if it didn’t help, I will assist you further.

thankyou

Very good How about if the word starts with c

Uhm and why do you do M equals A equals 2 T equals 2 I don't get it.and does this apply to all worded problems just like this but with a different word?

How can you know which is combination or permutation? Any tips? Please help

@zyl7521

permutation is when the arrangement is important and combination is when arrangement is not important. this video is helpful but go to organic chemistry's video to know what I'm talking about

If we have 2 factorial then we need to stop at 2 factorial...

Why 8?

The question says the vowels should always be together, so Consider vowels as one group and the other 7 consonants as 7 groups. So 7 consonants + 1 vowel = 8

@@ynnagesite5678 Because when we say vowels are always together, when there is a word together, it means one group, well logically speaking. Therefore, the vowels AAEI from the word MATHEMATICS are equal to one group. Vowels are always together = 1 And the rest which are not vowels are not equal to one group, therefore we count them. We take the vowels out which we have left with: MTHMTCS And that is equal to 7 letters. 1 vowel group + 7 letters = 8 total.

Please do not waste time by expanding factorial such as 11 or 8 etc. None of the competitive exams will be interested in solving the big factorial. Moreover the logic matters and not the expansion of factorial.

You Wrote 8 instead Of 7 in the 2nd word problem
