the time failures for an electronic component are exponentially distributed with a mean of 50 hours between consecutive failures
alisha [4.7K]

Using the exponential distribution, it is found that there is a 0.3297 = 32.97% probability that a randomly selected part will fail in less than 20 hours.

<h3>Exponential distribution</h3>

The exponential probability distribution, with mean m, is described by the following equation:

f(x) = \mu e^{-\mu x}

In which \mu = \frac{1}{m} is the decay parameter.

The probability that x is lower or equal to a is given by:

P(X \leq x) = \int\limits^a_0 {f(x)} \, dx

Which has the following solution:

P(X \leq x) = 1 - e^{-\mu x}

In this problem, the mean and the decay parameter are, respectively, given by:

m = 50, \mu = \frac{1}{50} = 0.02.

The probability that a randomly selected part will <u>fail in less than 20 hours</u> is given by:

P(X \leq 20) = 1 - e^{-0.02 \times 20} = 0.3297

0.3297 = 32.97% probability that a randomly selected part will fail in less than 20 hours.
