probability

n(E)=(n+1)*(2)ⁿ
n(S)=2^n+m
P=n(E)/n(S) =(n+1)/2^m
cheers!!

gordo luk carefully i think u r repeatedly considering some cases

i eat back my words..yeah msp, as cel. said, its terrible extra counting dat ive done, dis is the wrong method..., working it out..all over again...,

kk

msp is ur buk ans some wat like

Σ xCy . r

im gettin terribly dirty solution

(n+2)/2^m+1 ????????

pls point out mistake sir..[2][2]

sir the author has assumd m>n sir in his hint.
