Question

what is the theoretical probability of randomly picking a square from the shapes below?

Explanation:

Step1: Count total shapes

There are 6 shapes in total.

Step2: Count square shapes

There are 4 square shapes.

Step3: Calculate probability

The probability formula is $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P = \frac{4}{6}=\frac{2}{3}$.

Answer:

$\frac{2}{3}$
