Re: Binomial Theorem IIT JEE

As you have asked for the practice questions for Binomial Theorem for JEE exam, I am providing you with it

The number of terms in the expansion of (x + y)n is

(a) one more than the index
(b) one less than the index
(c) same as index
(d) none of these

Q2. nCr + nCr-1 =

(a) nCr-1
(b) n+1Cr
(c) n+1Cr+1
(d) n+1Cr-1

Q3. The general term in (x + y)n is given by

(a) Tr+1 = nCrxn-r.yr
(b) Tr+1 = nCr-1xn-r.yr
(c) Tr+1 = nCrxn-r.yr
(d) none of these

Q4. The middle term in expansion of (x + y)n, in case of n being odd is

(a) (n+3)/2 th
(b) n/2 th
(c) (n/2 + 1) th
(d) (n+1)/2 th and (n+3)/2 th
