Find the value of
Answer to Problem 90E
The value of
Explanation of Solution
Calculation:
Consider that
Hypergeometric distribution:
A discrete real valued random variable Y is said to follow hypergeometric distribution if the probability mass function of Y is,
Where integer y takes value from 0, 1, 2, …, n with the conditions
Consider that
Then, the marginal probability functions of
The joint probability distribution of
Thus, the marginal probability distribution of
Thus, the marginal probability distribution of
Now, the marginal probability distribution of
Thus, marginal probability distribution of
For a random variable,
Thus, the value of
Similarly, the value of
Now, using the joint probability distribution of
Thus, the value of
Thus, the value of
