A bag contains 1 red and 7 white marbles. A marble is drawn from the bag and its colour is observed. Then the marble is put back into the bag and the contents are thoroughly mixed. Using a) the Binomial distribution; and b) the Poisson approximation to Binomial distribution, find the probability that in 8 such drawings a red ball is selected exactly 3 times.

Solution:
Total number of marbles in bag (1 red + 7 white) is total 8 marbles
Number of red marbles is 1
Marbles are draw without replacement
Ans: the probability of 8 such drawings a red ball is selected exactly 3 times is 24.
