Each expression evaluation begins from these definitions. Any alterations during the evaluation of the

expression is lost after the conclusion of the evaluation of that expression, although the alteration does

hold in effect until the end of that evaluation.

26) A bag of marbles contains 10 marbles. They are all white marbles with black numbers written on

them. The numbers are 3, 2, 3, 5, 1, 6, 3, 2, 4, 1. You reach into the bag with one hand and grab two

marbles. List all of the possible pairs of numbers of the two marbles in your hand.

27) You are creating an array of two numbers. A bag of marbles contains 5 marbles. They are all white

marbles with black numbers written on them. The numbers are 3, 2, 3, 5, 1. You reach into the bag and

grab one marble. You record the number in the 0 th position of the array. Set this marble to the side.

Now you reach in a second time and grab one marble. You record the number in the 1 st position of the

array. List all of the possible arrays that could be made.
