In this paper, first we obtain some inequalities for the maximum of partial sums ∑nk=1Xn where{Xn ,n≥1} is a sequence of NEGATIVELY DEPENDENT (ND) RANDOM VARIABLES. Then we apply these inequalities to generalized some classical strong limit theorems in probability, if E[Xn │Fn-1]=0, and Fn =σ(X1 ,X2 ,…Xn), for every n≥1.
