Anyone can help with this

Please show the R code.

Thanks!

In a large city, telephone calls to 911 come on the average of two calls every 5 minutes. At 11:15 pm, 911 received a call for an emergency request. Since then, no calls came for next 40 minutes. What is the the probability that 911 would receive a call before midnight? Redo this question by using R. (Make sure to use perp function in R) You need to type two lines for this answer: one is R code in terms of the conditional probability, the other is R code with the unconditional probability expression reflecting on the memoryless property.
