  • 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.
