(a): Marginal pmf of x
(b): Marginal pmf of y
(c): Mean and Variance of x
(d): Mean and Variance of y
(e): The covariance and the coefficient of correlation
Step-by-step explanation:
Given
<em>x = bottles</em>
<em>y = carton</em>
<em>See attachment for complete question</em>

Solving (a): Marginal pmf of x
This is calculated as:
So:
Solving (b): Marginal pmf of y
This is calculated as:
So:
Solving (c): Mean and Variance of x
Mean is calculated as:
So, we have:
Variance is calculated as:
Calculate
So:
Solving (d): Mean and Variance of y
Mean is calculated as:
So, we have:
Variance is calculated as:
Calculate
So:
Solving (e): The covariance and the coefficient of correlation
Covariance is calculated as:
Calculate E(xy)
This gives:
So:
The coefficient of correlation is then calculated as:
--- approximated
