62it is necesary to know the least count of the marks.
Otherwise It cannot be solved!
62a+b+c+d+e+f = 240
0<= a, b, c, d, e, f <= 100
Hint : this can be found by binomial expanion.
Can it be?
13co-eff of x240
in(x+x2+....x100)6
x6(1+x2+....+x99)6(1-x)6
or, ___________________
(1-x)6
or, x6(1-x100)6(1-x)-6
then expand.......easy(i don think so...)
62this now comes from -ve binomial... 3
whihc by the way is not in syllabus!
24not in syllabus??????????????then how can we do multinomial questions like this one?????
62for some of those questions eureka.. the question is simpler..
-ve binomial is not in syllabus. Have no doubt about it.
