Question 05 (b)
In a room two different lightbulbs and are installed. According to the packaging, lightbulb fails before time with probability ( in months). Lightbulb has a probability density function for the failure time given by
Determine the constant of the probability density function for the failure time of lightbulb ?
Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you?
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it!
Since is a probability density function, what does need to be?
Checking a solution serves two purposes: helping you if, after having used the hint, you still are stuck on the problem; or if you have solved the problem and would like to check your work.
Since is a probability density function, Hence,
