The lifetime of a semiconductor laser is normally distributed with a mean of 7000 hours and...

The lifetime of a semiconductor laser is normally distributed with a mean of 7000 hours and a standard deviation of 600 hours. A product contains three lasers, and the product fails if any of the laser fails. Assuming that the lasers fail independently, would the product lifetime exceed 10,000 hours of use before failure with a probability of 99%. If not, recommend a n alternative lifetime distribution for the lasers.

the lifetime of a certain battery has an unknown distribution with mean value 8 hours and a standard deviation of 2 hours. what is the probability that the average battery lifetime of a sample of 36 batteries will be greater than 8.1 hours? I know by the CLT that at 36 trials the sample mean will follow a normal distribution but i cant remember how to calculate the variance of this distribution nor do i know where to go from...
