Algebra.Com's Answer #333985 by stanbon(75887) ![]() You can put this solution on YOUR website! a mini license plate for a toy car must consist of two letters followed by a one digit odd number. Each letter must be a P,Q,or a R. repetition of letters is not permitted. \n" ); document.write( "------ \n" ); document.write( "# of ways to arrange the letters: 3! = 6 \n" ); document.write( "# of ways to select an odd digit: 5 \n" ); document.write( "===== \n" ); document.write( "a)use the counting principle to determine the number of points in the sample space. \n" ); document.write( "Ans: 6*5 = 30 \n" ); document.write( "------------------------ \n" ); document.write( "b)construct a tree diagram to determine the number of points in the sample space.( i am having horrible trouble trying to do a tree diagram.) \n" ); document.write( "Ans: 30 \n" ); document.write( "at ------------------ \n" ); document.write( "c)list the sample space. \n" ); document.write( "I'll list the branch that starts with \"P\". \n" ); document.write( "PQ1,PQ3,PQ5,PQ7,PQ9,PR1,PR3,PR5,PR7,PR9 \n" ); document.write( "-- \n" ); document.write( "Then you have 10 more that start with R \n" ); document.write( "Then you have 10 more that start with Q \n" ); document.write( "============================================= \n" ); document.write( "d)determine the exact probability of creating a mini license plate with a Q. \n" ); document.write( "give solution exactly in reduced fraction form. \n" ); document.write( "Ans: 10/30 = 1/3 \n" ); document.write( "======================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
