Algebra.Com's Answer #812159 by math_helper(2461)![]() ![]() You can put this solution on YOUR website! Total number of marbles: 4+3+6 = 13 \r \n" ); document.write( "\n" ); document.write( "a) There are 4 outcomes (of 13 possible) for choosing blue: 4/13 for choosing blue. \n" ); document.write( "That leaves 12 marbles in the bag, of which 6 are red, so 6/12 for choosing red on the 2nd choice. \n" ); document.write( " \n" ); document.write( "P(blue then red) = (4/13)*(6/12) = 2/13 \r \n" ); document.write( "\n" ); document.write( "Parts (b) and (c) are solved in a similar manner.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
