The resistance of a copper wire increases by a factor of 1.62 when current flows through the wire compared to its resistance when no current flows and its temperature is 20o C. What is its temperature when the current flows?
Suppose that the lifetimes of electric light bulbs follow an Exponential distribution with mean
1000 hours. A
random sample of 40 light bulbs is tested. The probability that the mean
lifetime is at least 900 hours is:
A platinum resistance thermometer consists of a coil of 0.10-mm-diameter platinum wire wrapped in a coil. (a) What is the length of the wire needed so that the coil’s resistance at 20o C is 25 Ω. The resistivity of platinum at this temperature is 1.0 x 10-7 Ω.m. (b) What is the temperature of this platinum wire when its resistance increases 35% of its initial temperature? The temperature coefficient of resistivity for platinum is 3.92 x 10-3 /o C.

There are 10 girls and 7 boys in a class and need to select 4 students as a school representative. In how many ways can we select of 2 girls and 2 boys?
A store contains 1 pair of boots with each of the following colors are black, chocolate and yellow. Each pair is put together in a particular place. You enter into the dark store and pick randomly the boot without looking at it. Then, you replace it with another boots. What is the probability that you will choose the black pair of boots both times?
