Please write the R code Thank you for your concern

3. Customer arrivals to a fast food restaurant can be modeled by a Poisson process. The busiest time of the restaurant is between 19:00 p.m. and 19:30 p.m. with an arrival rate of ;=4 customer /min. a) By writing an R code, compute the probability that at least 131 customers arrive between 19:00 p.m. and 19:30 p.m. b) The management wants to compute an upper limit C such that the number of customers arriving between 19:00 p.m. and 19:30 does not exceed C with a probability of at least 0.99. Compute the upper limit C by writing an R code. Note: The codes above may be single-line codes (one command)
