\n" ); document.write( "Given: There are 12 red pens.

\n" ); document.write( "Given: The probability of getting a red pen is twice the probability of getting a blue pen.
\n" ); document.write( "Conclusion: The number of blue pens is half the number of red pens -- 6.

\n" ); document.write( "Given: The probability of getting a red pen is three times the probability of getting a green pen.
\n" ); document.write( "Conclusion: The number of green pens is one-third the number of red pens -- 4.

\n" ); document.write( "ANSWER: The total number of pens in the box is 12+6+4 = 22

\n" ); document.write( "
\n" ); document.write( "
