Algebra.Com's Answer #829948 by math_helper(2461)![]() ![]() You can put this solution on YOUR website! \r \n" ); document.write( "\n" ); document.write( "To find the probability of x, P(x), count or compute the number of favorable outcomes and divide it by the total number of possible outcomes.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "1. P(green or red) = (2+18)/38 = 20/38 = 10/19 or about 0.5263\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "2.
