If one of the 87 flights is randomly selected, find the probability that the flight selected arrived on time given that it was and Upstate Airlines flight.
_____________On Time Flights _________________ Late Flights
Podunk ___________ 33 ___________________________ 6
Upstate____________43 ___________________________ 5

Are you studying Markov's chains?
let's set up a transition matrix
33/87 6/87
43/87 5/87
let's multiply [0 1] by this matrix to get
[ 43/87 5/87]
(first number represents ontimeUpstate)
so how about 43/87 or .4943 ?
Not absolutely sure about this.
