MCQ
${C_0} - {C_1} + {C_2} - {C_3} + ..... + {( - 1)^n}{C_n}$ = . . .
- A${2^n}$
- B${2^n} - 1$
- ✓$0$
- D${2^{n - 1}}$
Putting $x = -1$, we get ${(1 - 1)^n} = {\,^n}{C_0} - {\,^n}{C_1} + {\,^n}{C_2} - .....{( - 1)^{n\,\,n}}{C_n}$
Therefore ${C_0} - {C_1} + {C_{_2}} - {C_3} + ....( - 1){\,^n}{C_n} = 0$
