1.If (nr)\binom{n}{r}(rn) denotes the combination of nnn things taken rrr at a time, then the value of (9997)+(9896)+(9795)+⋯+(31)+(20)\binom{99}{97} + \binom{98}{96} + \binom{97}{95} + \cdots + \binom{3}{1} + \binom{2}{0}(9799)+(9698)+(9597)+⋯+(13)+(02) equals:a.(9997)\binom{99}{97}(9799)b.(10098)\binom{100}{98}(98100)c.(9998)\binom{99}{98}(9899)d.(10097)\binom{100}{97}(97100)Login to continueOnly logged in users canattempt or see the solution.
