Kindly show complete solution. Excel can be used.
Transcribed Image Text:A small-business Web site contains 100 pages and 60%, 30%, and 10% of the pages
contain low, moderate, and high graphic content, respectively. A sample of four pages is
selected without replacement, and X and Y denote the number of pages with moderate
and high graphics output in the sample.
The following is the generated joint probability distribution (incomplete):
x = 0

Transcribed Image Text:The P(X = 3 and Y = 1) is equal to
|(expressed in 5 decimal places).
The mean of the marginal distribution of X is

significant figures or one 1 decimal place).
The conditional mean of the number of high graphic output pages (Y) given only one
moderate graphic output page (X = 1) is
|( expressed in 3 decimal
