Question

draw a card from a box filled with numbered cards. cards are returned and shufled after each selection. whats the probability of drawing a card with a 10 or higher?

Explanation:

Step1: Count total number of cards

Count the number of cards in the box. There are 12 cards in total.

Step2: Count number of cards with 10 or higher

Count the number of cards with 10 or higher. There are 3 cards with 10.

Step3: Calculate probability

The probability formula is \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). So \(P = \frac{3}{12}\).

Step4: Convert to percentage

\(\frac{3}{12}=0.25\), and \(0.25\times100\% = 25\%\)

Answer:

25%
