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