You pick a number between 2 and 6 at random (each with probability 1/5) and your friend picks a number between 3 and 8 at random (each with probability 1/6). what is the expected value of the sum of six times the number you picked and five times the number your friend picked? for instance, if you picked 4 and your friend picked 3 the sum would be 24 + 15 = 39.
