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.
Answer
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:
$0.2$
