An urn contains six red balls, five white balls, and four black balls. Three balls are drawn from the urn at random without replacement. For each red ball drawn, you win $8, and for each black ball drawn, you lose $12. Let X represent your net winnings.
\n" ); document.write( "Compute E(X), your expected net winnings.
\n" ); document.write( "E(X) =
\n" ); document.write( "Solution:
\n" ); document.write( "Use the hypergeometric distribution to compute the probabilities.
\n" ); document.write( "probability = where r+w+b = 3\r
