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.

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.

@varantsovgevorgyan5798 4 жыл бұрын

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.

Word problem no 3 is absolutely wrong because combination of vowels is not considered please judge ur answer and dont ignore it because many jee advanced students learn this .thank you so much for ur content

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

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

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

Professional Gamer can you explain further more

@baconl101 4 жыл бұрын

@@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.
