Following are three sets of letters. Draw one letter from Set 1 and place it in Set 2. Then draw one letter from Set 2 and place it in Set 3. Finally, draw a letter from Set 3. What is the probability that the last letter drawn is a B?

\n" ); document.write( "BCB
\n" ); document.write( "Set 2
\n" ); document.write( "BB
\n" ); document.write( "Set 3
\n" ); document.write( "B
\n" ); document.write( "----
\n" ); document.write( "To fail to get a \"B\" you would have to get the C from set1 to set2 to set3
\n" ); document.write( "---
\n" ); document.write( "P(C out of 3) = (1/3)*(1/3)(1/2) = 1/18
