You can put this solution on YOUR website!
for both green it is (7/12)(7/12) with replacement or 49/144, or 0.3403.\r
\n" ); document.write( "\n" ); document.write( "at least 1 green is 1-0 green probability. For 0 green for both cards it is (5/12)^2 or 25/144, so the answer is 119/144 or 0.8264 probability.
\n" ); document.write( "That is also the 0.3403 above + 2 (7/12)(5/12) or 70/144 or 0.4861
\n" ); document.write( "That plus 0.3403 is 0.8264.\r
\n" ); document.write( "\n" ); document.write( "Given G1 is green the probability G2 is green is 7/12 with replacement. Nothing has changed, and the trials would be independent, in that what happened on the first doesn't affect the second.
\n" ); document.write( "
\n" );
