Answer:

15 $x^{3}$ y + 6 $x^{2}$ $y^{2}$ + 9x $y^{3}$

Step-by-step explanation:

multiple everything in the brackets by 3xy

3xy x 5 $x^{2}$ = 15 $x^{3}$ y

3xy x 2xy = 6 $x^{2}$ $y^{2}$

3xy x 3 $y^{2}$ = 9x $y^{3}$

15 $x^{3}$ y + 6 $x^{2}$ $y^{2}$ + 9x $y^{3}$

Step-by-step explanation:

Given: A number cube is rolled and a coin is flipped.

Now, the required sample space will be
