Given information
The average lifetime of light bulbs is 1000 hours.
The mean () of the exponential density function representing the probability of failure is 1000.
Step-by-step explanation
Step 1.
- Write the exponential probability distribution having mean ( ).
- Write the probability of failure of bulbs represented by an exponential density function having mean by substituting 1000 for .
