3.52: Marginal Distribution | Probability & Statistics for Engineers & Scientists by Walpole 9th Ed

This video describes the conceptual overview related to the marginal distribution in the form of problem 3.52 to calculate different values for continuous probabilities. In this problem, the use of joint probability distribution and marginal distribution has been used to find conventional probabilities.
3.52 A coin is tossed twice. Let Z denote the number of heads on the first toss and W the total number of heads on the 2 tosses. If the coin is unbalanced and a head has a 40% chance of occurring, find
(a) the joint probability distribution of W and Z;
(b) the marginal distribution of W;
(c) the marginal distribution of Z;
(d) the probability that at least 1 head occurs.
