There are 8 cards in total.

Step2: Identify prime - numbered cards

Prime - numbered cards are 2, 3, 5, 7. So there are 4 prime - numbered cards.

The probability formula is $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Here, $P(\text{prime})=\frac{4}{8}=\frac{1}{2}$.

Step4: Convert to percentage

To convert a fraction to a percentage, we multiply by 100. So $\frac{1}{2}\times100 = 50%$.
