10. Resistors are labeled 100Ω. In fact, the actual resistances are uniformly distributed on the interval [96,102].
a. Find the probability that the resistance is between 97Ω and 100 Ω
b. Suppose that resistances of different resistors are independent. What is the probability that two
out of seven resistances are between 97Ω and 100Ω ?

(5.38) The design of an electronic circuit calls for a 100-ohm resistor and a 250-ohm resistor connected in series so that their resistances add. The components used are not perfectly uniform so that the actual resistances vary independently according to normal distributions. The resistance of 100-ohm resistors has mean 100 ohms and standard deviation 2.5 ohms, while that of 250-ohm resistors has mean 250 ohms and standard deviation of 2.8 ohms. (a) What is the distribution of the total resistance...

If a person takes the bus 30 times a month commuting between his dorm and the Dining Hall. It takes the bus 10 minutes to run one loop. The waiting time, in minutes, for a bus to arrive is uniformly distributed on the interval [0, 10]. Suppose that waiting times on different occasions are independent. What is the standard deviation of the mean waiting time in minutes of a month? Round your answer to three decimal digits. What is the...
