Many electronics follow a failure rate described by an exponential probability density function (PDF).Solar panels are advertised to last 20 years or longer, but panels made in China are failing at a higher rate.The time-to-failure of this device is usually exponentially distributed with mean 7 years.
What is the probability of failure in the first 6 years?
Four decimal places.
