Answer
Explanation:
Step1: Calculate the proportion of chipped vases
The proportion of chipped vases in the first - batch is $\frac{2}{20}=\frac{1}{10}$.
Step2: Use the proportion to predict for the next batch
If the proportion holds, for 10 vases, the expected number of chipped vases is $10\times\frac{1}{10}=1$.
