Select 4 words from the word ASSASSINATION.Please solve it using multinomial theorem
I think this is the way to solve this type of problems…!!
ASSASSINATION : 3 a : (1 +x + x^2 )
4 S : (x + x^2 + x^3 + 1)
2 I : (x + 1)
2 N : (x + 1)
1 T and 1 O : both can be represented by 1
Hence find coefficient of x^4 in
(x + x^2 + 1) (x + x^2 + x^3 + 1) (x + 1) (x + 1) (
Apply multinomial theorem now
but the way you applied it is wrong as each element should be divded by n! since the words are repeated here
given answers is 71
Yes ofcourse u need to permute… i just did the selection part.
Please post the question as written.
If the ques is –
