Notation: P(Red) denotes the probability of selecting a red ball\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "First, add up the number of balls to get a total of 3+4+5=12 balls total.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "P(Red) = Number of Red Balls/Number of Balls Total = 3/12 = 1/4\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the probability of selecting a red ball is 1/4 which is 0.25 in decimal form giving us a 25% chance. \n" ); document.write( " |
