Hi everyone so I have a quick question.
Say for example we have a supermarket in which customers arrive with an intensity of 10 per hour.
The supermarket has 3 aisles, A,B and C. The probability of a customer going going to each aisle is 0.6,0.3,0.1
Then we want to find out the expected waiting time for 2 customers to go to aisle A, how would I go about this?
Am I just doing P(X=2) = 1-P(X<=1) firstly or ?
Haven't done questions like this before !
See I am trying to figure out how would I calculate it because it's a bit confusing for me in terms of how to go about it
