_____________On Time Flights _________________ Late Flights
Podunk ___________ 33 ___________________________ 6
Upstate____________43 ___________________________ 5

Answer 1

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 ontime-Upstate)

so how about 43/87 or .4943 ?

Not absolutely sure about this.
