Ross, Sheldon M. Improved Chen-Stein bounds on the probability of a union. (English) Zbl 1358.60040 J. Appl. Probab. 53, No. 4, 1265-1270 (2016). Summary: We improve the Chen-Stein bounds when applied to the probability of a union. When the probability is small, the improvement in the distance from the lower to the upper bound is roughly a factor of 2. Further improvements are determined when the events of the union are either negatively or positively dependent.
