P=0.17. Var(L2-L1)

'VVI Let A= last 2 digits of your student id. Let p=A/100. For example my student id is 9227320 my Your a A=20 and my p=20l100=.2 autom What is your p= 0.17 Recall bus ridership homework question. Now assume that at each stop assume you either have no one get on or1 person get on. The probability of no one getting on is p = A/lOO from above. The probability that someone gets off the bus is 0.47 Assume before stop 1 you have an empty bus, let L1 be the number of people on the bus at stopl and L2 the number of people on the bus at stop 2. Calculate analytically Var(2L1L2) showing all you work
