Question

In how many ways an examiner can assign 30marks to 8 questions, giving not less than 2 marks to any question​

Answer 1

Answer:

Give 2 marks to all 8 questions first... You given total 16 marks...

Now only 14 marks left...

Now you have to give 14 marks to 8 questions without any condition on the left marks....

So it's equivalent to fill 14 balls in 8 bags...

Applying the same concept...

It is.... {14+(8-1)}!/14!(8-1)!

21!/14!7!

=116280...

I may be wrong....
