### Warranty Performance Analysis
A manufacturer of consumer electronics expects 2% of units to fail during the warranty period. A sample of 500 independent units has been tracked for warranty performance.
**Problem Statement:**
(a) What is the probability that none will fail during the warranty period?
(b) What is the expected number of failures during the warranty period?
(c) What is the probability that more than 2 units will fail during the warranty period?
---
**Answers:**
**(a)** The probability that none will fail during the warranty period:
\[ \text{Probability} = 0.1277 \]
*Rounded to four decimal places.*
**(b)** The expected number of failures during the warranty period:
\[ \text{Expected Number} = 10 \]
*Rounded to the nearest integer.*
**(c)** The probability that more than 2 units will fail during the warranty period:
\[ \text{Probability} = 0.9974 \]
*Rounded to four decimal places.*
