The numbers on the cards are 1, 2, 3, and 4. Among these numbers, the prime numbers are:
- 2 (which is prime)
- 3 (which is prime)
So, there are 2 prime numbers out of the total of 4 cards.
To find \( P(\text{prime}) \):
\[
P(\text{prime}) = \frac{\text{Number of prime numbers}}{\text{Total number of cards}} = \frac{2}{4} = 0.5
\]
To express this as a percentage, we multiply by 100:
\[
P(\text{prime}) = 0.5 \times 100 = 50\%
\]
Thus, the probability of picking a prime card is **50%**.
