Calculate the expected value of red marbles out of a bag containing 6 red marbles and 8 blue marbles if you are taking 4 from the bag.
here for hypereometric distribution parameter n=sample size =4 , m=number of red balls =6 and N =total balls =14
therefore expected value of red marbles =nm/N =4*6/14=24/14=12/7 =1.7143

There are 3 green marbles and 5 blue marbles in a bag and 4 red marbles. Two marbles are drawn from the bag at random without replacement. Find the probability that both marbles are blue. Find the probability that the first is blue and the second green.
(Adapted from Tolga Tasdizen): We have a bag with 5 red marbles
and 9 blue marbles. You draw three marbles out of the bag without
replacement.
(a) What is the probability that you got a red, blue, and red
marble in that order? Hint: use the multiplication rule to get the
size of the sample space (and size of the event set) as if the
marbles were distinguishable.
(b) What is the probability of not getting any blue marbles?
(c)...
