- Suppose that the distribution of the lifespan of an item has the hazard rate function λ(t) = t3. What is the probability that: (a) the item survives to age 2? (b) a 1-year-old item will survive to age 2?arrow_forwardSuppose that an item has a hazard rate function X(t) = 2.4t², t> 0. What is the probability that (a) the item survives to age 0.5? (b) the item's lifetime is between 1.5 and 3? (c) a (-year-old item will survive to age 3?arrow_forwardThe failure time (T) of an electronic circuit board follows exponentially distribution with failure rate λ = 10−4/h. What is the probability that (i) it will fail before 1000 h? (ii) it will survive at least 10,000 h ? (iii) it will fail between 1000 and 10,000 h? (iv)Determine the mean time to failure. .arrow_forward
- The pdf of the time to failure of an electronic component in a copier (in hours) is f (x) = [exp (-x/3100)]/3100 for x > 0 and f (x) = 0 for x ≤ 0. Determine the probability that:(a) A component lasts more than 1180 hours before failure.(b) A component fails in the interval from 1180 to 2010 hours.(c) A component fails before 3010 hours.(d) Determine the number of hours at which 11% of all components have failed.(e) Determine the mean.Round your answers to three decimal places (e.g. 98.765).arrow_forwardThe probability that a vehicle will enter an intersection within a period of x minutes is given by P(x) = 1 -e-0.1x Determine symbolically the elapsed time x when there is a 50-50 chance that the vehicle has entered the intersection. The elapsed time is approximately min. (Type an integer or decimal rounded to two decimal places as needed.)arrow_forwardNext question When a man observed a sobriety checkpoint conducted by a police department, he saw 662 drivers were screened and 9 were arrested for driving while intoxicated. Based on those results, we can estimate that P(W) = 0.01360, where W denotes the event of screening a driver and getting someone who is intoxicated. What does P (W) denote, and what is its value? What does P (W) represent?arrow_forward
- A individual, with a utility function lnW and an initial wealth level W0, is faced with a fair gamble of winning or losing $h (where W0 > h > 0) with 50-50 chance. (a) Is this individual risk averse? Explain.(b) Suppose that the individual is willing to pay up to an amount of f in order to avoid such a gamble. Give the equation that determines f, and solve the equation for f (i.e., express f in terms of W0 and h). (c) Show that f increases as h increases.arrow_forwardThe lifetime, t, in hours, of an alkaline battery is exponentially distributed with ? = 0.10 per hour. What is the probability that the battery will last more than 18 hours?arrow_forwardThe probability that at a filling station one has to wait more than 7 minutes for the service is 0.14. Given the waiting time is exponentially distributed find the probability that we are served in 3 minutes after arrival.arrow_forward

(i) What is the probability that an aquatic insect lives longer than 12 hrs? (ii) What is the median of this distribution? (50% live less time and 50% live longer) (iii) Assume the lifetimes of these insects are independent of each other. What is the probability that at least 35 of the next 100 insects live longer than 12 hrs?arrow_forwardThe time between customer arrivals at a furniture store has an approximate exponential distribution with mean θ = 8.5 minutes. If a customer just arrived, find the probability that the next customer will not arrive for at least 20 minutes.arrow_forward
