Algebra.Com's Answer #594670 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! There are 20 marbles \n" ); document.write( "Prob of blue is (12/20) and green is (2/20). There is no joint probability, so the answer is 0.7 \n" ); document.write( "For a blue and a red, the numerators are 12 and 6, so the probability is 0.9\r \n" ); document.write( "\n" ); document.write( "There are 36 outcomes, and they form a pyramid with \n" ); document.write( "roll 2=1 \n" ); document.write( "3=2 \n" ); document.write( "4=3 \n" ); document.write( "5=4 \n" ); document.write( "6=5 \n" ); document.write( "7=6 \n" ); document.write( "8=5 \n" ); document.write( "9=4 \n" ); document.write( "10=3 \n" ); document.write( "11=2 \n" ); document.write( "12=1\r \n" ); document.write( "\n" ); document.write( "The probability of rolling a 7 is (1/6) \n" ); document.write( "The probability of a 5 or a 11 is also (1/6) from the above. \n" ); document.write( " |
