Geometric shapes are drawn on cards as shown. The cards are placed in a box. A card is randomly selected.

Question

The picture shows 12 cards. 4 cards have circles on them. 3 cards have diamonds on them. 5 cards have triangles on them.
What Is the probability of selecting a card with a triangle?
Enter a number in the box.

Answer 1

To calculate the probability of selecting a card with a triangle, you can use the formula for probability:

\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]

In this scenario:

• The number of cards with triangles = 5
• The total number of cards = 12

Now, apply the values to the formula:

\[ \text{Probability of selecting a triangle} = \frac{5}{12} \]

So, the probability of selecting a card with a triangle is \(\frac{5}{12}\).

If you need the answer in decimal form, you can calculate:

\[ \frac{5}{12} \approx 0.4167 \]

However, as per your request, you'll likely want to enter \(\frac{5}{12}\) or the decimal 0.4167 in the box as your answer.
