Question
The commulative distribution of a component is given as F(t) = 0.2e^(-0vt) of the range of the random variable T= 3 ≤ t ≤ αbr Determine the mean time to failure MTTF What is the probability that the component will fail 10hrs
Solution
The question seems to be incomplete. The cumulative distribution function F(t) = 0.2e^(-0vt) seems to have a typo. The '0v' in the exponent does not make sense. If we assume it to be '0.2t', the function becomes F(t) = 0.2e^(-0.2t).

Mean Time To Failure (MTTF) is the expected value of a non-negative random variable. For an exponential distribution, the MTTF is the reciprocal of the rate parameter. In this case, the rate parameter is 0.2, so the MTTF is 1/0.2 = 5 hours.

The probability that the component will fail by 10 hours is given by the cumulative distribution function at t=10. So, we substitute t=10 into F(t) to get F(10) = 0.2e^(-0.2*10) = 0.2e^-2 = 0.2 * 0.135 = 0.027. So, the probability that the component will fail by 10 hours is 0.027 or 2.7%.
Please correct the function if my assumption is not correct.
