Keisha has a bag that contains one red marble (r), one yellow marble (y), one green marble (g), and one orange marble (o). she makes the table below to show the different ways that she can choose two marbles, by first choosing one marble, replacing it, and then choosing another marble.

what outcome is missing from keisha’s table?

The outcome that is missing in the Keisha's table is:

yy

Step-by-step explanation:

We know that element in each table is written as the expression in terms of variable of different colors where the first term of the expression is the variable that represents the color of first marble and the second term of the expression is the variable that represents the color of the second marble.

The table could be represented as:

                                                   Second marble

                                 red(r)      yellow(y)      green(g)    orange(o)

            red(r)               rr               ry                rg                ro  

First     yellow(y)         yr             yy                yg               yo

marble  green(g)         gr              gy                gg              go

             orange(o)       or              oy                og              oo        

Hence, the missing term in the table is:

yy
