help me please and thank you

Assume that the probability of the binomial random variable will be approximated using the normal distribution. Describe the area under the normal curve that will be computed. Find the probability that there are exactly 13 defective parts in a shipment. What is the area under the normal curve that describes the probability that there are exactly 13 defective parts in a shipment? O A. The area to the right of 12.5 O B. The area to the left of 12.5 O C. The area to the right of 13.5 O D. The area to the left of 13.5 O E. The area between 12 5 and 13.5
