document.write( "Question 1089624: You randomly select 2 marbles from a mug containing 7 blue marbles, 3 red marbles, and 2 white marbles. How many times greater is the probability of selecting 2 red marbles when you replace the first marble before selecting the second marble than when you do not replace the first marble before selecting the second marble?

You can put this solution on YOUR website!
A = P(RR) without replacement = (3/12)*(2/11) = 6/132 = 1/22
\n" ); document.write( "B = P(RR) with replacement = (3/12)*(3/12) = 9/144 = 1/16
\n" ); document.write( "So B/A = (1/16)/(1/22) = 3.175 \n" ); document.write( "

\n" );
