some sanitation workers sifted through some recycling and trash to see whether people had correctly sorted their plastic bottles. what is the probability that a randomly selected bottle is made of plastic #2 and is correctly placed? simplify any fractions.
Answer
Explanation:
Step1: Calculate total number of bottles
Total bottles = (2 + 5)+(3 + 5)=15
Step2: Identify number of desired - type bottles
Number of plastic #2 and correctly - placed bottles = 2
Step3: Calculate probability
Probability = $\frac{\text{Number of desired - type bottles}}{\text{Total number of bottles}}=\frac{2}{15}$
Answer:
$\frac{2}{15}$
