Bag A contains 2 red and 3 green balls.
a) Two balls are chosen at random from the bag without replacement. Find the probability
that 2 red balls are chosen.
Bag B contains 4 red and n green balls
b) Two balls are chosen without replacement from this bag. If the probability that two red
balls are (2)/(15), show that n=6.
A standard die with six faces is rolled. If a 1 or 6 is obtained, two balls are chosen from bag A,
otherwise two balls are chosen from bag B.
c) Calculate the probability that two red balls are chosen.
d) Given that two red balls are chosen, find the probability that a 1 or a 6 was obtained on the
die.
