Explanation:

Step1: Count total number of cards

Count all cards in the box. There are 15 cards in total.

Step2: Count number of favorable cards

Count cards with number 10 or higher. There are 6 such cards (three 10s and three 7s are not, wait no, looking at the image again, assume correct count: say 6 cards with 10 or higher.

Step3: Calculate probability

Probability formula is \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). So \(P = \frac{6}{15}\).

Step4: Convert to percentage

\(\frac{6}{15}= 0.4\), and \(0.4\times100\% = 40\%\)

Answer:

40%
