Probability

Natasha is performing some electrical work, and she is currently working on devices that deliver between 1200 and 1500 volts. Assume the voltage is evenly distributed in that range, and that the devices are independent. a] Let V represent the voltage in one device. What are the distribution, parameterls}, and support of V? b) Find the probability that a device delivers between 1250 and 1325 volts. {:3 Given that a device delivers less than 1400 volts, nd the probability it delivers more than 1300 volts. d) The devices with the highest 12% of voltages deliver at least how many volts? 2] What values cut off the middle 40% of voltages? f) Find the variance of V. 3) Find the probability that two devices both deliver more than 1400 volts
