Q 13: A company purchased components from three firms P, Q, and R as shown in the table below.
Firm | Total number of components purchased | Number of components likely to be defective |
---|---|---|
P | 1000 | 5 |
Q | 2500 | 5 |
R | 500 | 2 |
The components are stored together. One of the components is selected at random and found to be defective. What is the probability that it was supplied by firm R?
