Question

q 20.) a bag contains 10 shapes, 4 green squares, 3 red hearts, 2 blue triangles, and 1 yellow star. what is the theoretical probability of choosing a blue triangle? express your answer as a decimal.

Explanation:

Step1: Recall probability formula

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

Step2: Identify values

Total number of shapes = $4 + 3+2 + 1=10$. Number of blue triangles = 2.

Step3: Calculate probability

Probability = $\frac{2}{10}=0.2$

Answer:

$0.2$
