Please help me solve these using R (coding language)

2. Dr. Keaton is still terrible at throwing darts. Each time he throws a dart, there is a probability of 0.01 that he hits the bullseye. He throws 100 darts. a. Is it appropriate to use the Normal approximation to the Binomial here? Why or why not? b. Regardless of your answer to part a, use the Normal approximation to find the probability that Dr. Keaton hits the bullseye fewer than 2 times (that is, 1 or fewer times). c. Use the Binomial distribution to find the exact probability that Dr. Keaton hits the bullseye fewer than 2 times
