Question

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

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.
