Question

The lifelength Y (in years) of a memory chip in a laptop computer is a Weibull random variable with probability density

a) Exponential distribution
b) Normal distribution
c) Poisson distribution
d) Binomial distribution

Answer 1

The lifelength of a memory chip in a laptop computer follows an exponential distribution, which is often used to represent the amount of time until a specific event occurs.

Step-by-step explanation:

The lifelength of a memory chip in a laptop computer follows an exponential distribution. The exponential distribution is often used when we are interested in the amount of time until a specific event occurs, such as the length of time between emergency arrivals at a hospital or the length of long-distance phone calls. In this case, the average lifetime of the memory chip is the mean of the exponential distribution.
