Resistors A research group of engineers has determined that the probability density curve for the proportion of resistors that survive the first test:

f(x) = k*(x^2 - 2x + 1) for 0 < x < 1

but they need to know the value of k that makes this a valid probability density.
What is the value of k?

Solution

The answer is k=3. Please check the url for proof................................................ http://s9.postimage.org/bwmo4jhbz/cram.jpg
