Sir i am stuck for this question

I I I (c) In a quality control process, 2000 units are randomly selected each day from the production line to check for defects. It is known from past experience that the probability of having a defective unit is 0.05. If at any time. 110 or more defective units are detected, the promos is stopped in that day. Suppose that this screening process is performed for 7 consecutive days. Find the (approodmate) probability that. the production proom is stopped on exactly 2 days in this period
