a glass vase factory recently produced 4 vases that were chipped and 16 vases that were not. considering this data, how many of the next 10 vases would you expect to be chipped? vases
Answer
Explanation:
Step1: Calculate the proportion of chipped vases
The total number of vases produced initially is $4 + 16=20$. The proportion of chipped vases is $\frac{4}{20}=\frac{1}{5}$.
Step2: Calculate the expected number of chipped vases
We expect the same proportion to hold for the next 10 vases. So the expected number of chipped vases is $\frac{1}{5}\times10 = 2$.
