Question

probability model non
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 prime number?
prime = ?%
total trials: 0
total successes: 0
percent success: 0%

Explanation:

Step1: Count the total number of cards

There are 13 cards in total.

Step2: Identify prime numbers

The prime numbers among the cards are 7. So there are 3 prime - numbered cards.

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 (prime - numbered cards) is 3, and the total number of outcomes (total cards) is 13. \(P = \frac{3}{13}\approx0.23 = 23\%\)

Answer:

23%
