ANSWER:Solution:
Step 1 of 3:
The resistance of resistors are uniformly distributed on the interval (95,103).
We have to find
- The mean resistance
- The standard deviation of resistance.
- Probability that resistance is between 98 and 102 .
- If the resistance of different resistors are independent. What is the probability that 3 out of six resistors have resistance greater than 100.
