Answer:

Option C

Step-by-step explanation:

For the spinner,

Probability of spinning an even number = [tex]\frac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]

Favorable outcomes = even numbers on the spinner

                                   = 3

Total outcomes = Total numbers on the spinner

                          = 6

Probability of spinning an even number = [tex]\frac{3}{6}[/tex]

                                                                  = [tex]\frac{1}{2}[/tex]

For the cube,

Total outcomes = total numbers on the dice = 6

Favorable outcome = Odd numbers on the dice = 3

Probability of rolling an odd number on rolling a cube = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

Probability of spinning an even number on spinner and an odd number on a cube = [tex]\frac{1}{2}\times \frac{1}{2}[/tex]

         = [tex]\frac{1}{4}[/tex]

Percentage probability = [tex]\frac{1}{4}\times 100[/tex]

                                       = 25%          

Option C is the answer.
