Explanation:

Step1: Count the number of cards

There are 10 cards in total.

Step2: Count the number of multiples of 3

The multiples of 3 among the cards are 3, 6, 9. So there are 3 multiples of 3.

Step3: Calculate the probability

The probability formula is \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). Here, the number of favorable outcomes (multiples of 3) is 3, and the total number of outcomes (total cards) is 10. So \(P = \frac{3}{10}=0.3 = 30\%\)

Answer:

30%
