Final answer:
The question asks about the lifetime of computer(s) modeled as a Rayleigh variable with an average lifetime of 5 years.
Step-by-step explanation:
The question is asking about the lifetime of computer(s) modeled as a Rayleigh variable. This falls under the topic of probability and statistics in mathematics.
The average lifetime of the computer(s) is given as 5 years. A Rayleigh variable is a continuous random variable with a probability density function. In this case, the lifetime of the computer(s) is modeled as a Rayleigh variable with an average lifetime of 5 years.
