a factory robot recently examined some bulbs, of which 12 were flawed and 48 were not. considering this data, how many flawed bulbs would the robot be expected to find in a batch of 95 bulbs?\n\nflawed bulbs
Answer
Explanation:
Step1: Calculate the proportion of flawed bulbs
The total number of bulbs examined initially is $12 + 48=60$. The proportion of flawed bulbs is $\frac{12}{60}=\frac{1}{5}$.
Step2: Find the expected number of flawed bulbs in a new - batch
If there are 95 bulbs in a new batch, and the proportion of flawed bulbs is $\frac{1}{5}$, then the expected number of flawed bulbs is $\frac{1}{5}\times95 = 19$.
Answer:
19
