\n" ); document.write( "1) List all the possible ways Robert could have scored 12 points.

\n" ); document.write( "There is no value added in making a list of all the possible ways. I'll leave that to you.

\n" ); document.write( "There IS added value in seeing a logical way to determine the number of different ways 12 points could be scored. And making the complete list will be easy once that is done.

\n" ); document.write( "Note the following method can be used to logically make a count of the number of ways of using any set of three numbers to get a particular total.

\n" ); document.write( "(i) 4 3-point shots: 1 way
\n" ); document.write( "The 4 3-point shots is the whole 12 points; the number of 2-point shots must be 0

\n" ); document.write( "(ii) 3 3-point shots: 2 ways
\n" ); document.write( "The 3 3-point shots are 9 of the 12 points; there are 3 points left. The number of 2-point shots can be either 0 or 1

\n" ); document.write( "(iii) 2 3-point shots: 4 ways
\n" ); document.write( "The 2 3-point shots are 6 of the 12 points; there are 6 points left. The number of 2-point shots can be any number 0 to 3

\n" ); document.write( "(iii) 1 3-point shot: 5 ways
\n" ); document.write( "The 1 3-point shot is 3 of the 12 points; there are 9 points left. The number of 2-point shots can be any number 0 to 4

\n" ); document.write( "(iii) 0 3-point shots: 7 ways
\n" ); document.write( "The 3-point shots are 0 of the 12 points; there are 12 points left. The number of 2-point shots can be any number 0 to 6

\n" ); document.write( "The total number of ways of scoring 12 points with 3-, 2-, and 1-point shots is 1+2+4+5+7 = 19.

\n" ); document.write( "You can easily make the complete list from the above discussion.

\n" ); document.write( "2) What is the possibility of scoring 12 points with a free throw?
\n" ); document.write( "3) What is the possibility of scoring 12 points without a free throw?

\n" ); document.write( "These two questions have no mathematical meaning; \"possibility\" is not a number in math.

\n" ); document.write( "Presumably the questions that are asked should have been the probabilities that, if 12 points were scored, they were scored either with or without a free throw (1-point shot).

\n" ); document.write( "Those probabilities can easily be determined by examining the complete list of all 19 ways of scoring 12 points.

\n" ); document.write( "I leave that to you also.
