NettetThis is known as linearity of expectation, and holds even when the random variables X_i X i are not independent events. A fair six-sided die is rolled repeatedly until three sixes are rolled consecutively. What is the expected number of rolls? NettetLinearity of dilution is tested for each validated sample type and is considered to be good if results are 70–130% of the expected concentration for each dilution. Linearity is important for accurate measurement of analyte concentration across the …

NettetLinearity of Expectation : WTF. My friend gave me a problem, which can be reduced to the following. Let S ( k) be the set of all arrays of size n that contains k ones and n − k zeroes. Let for some array s ∈ S ( k) , p o s s [ 1.. k] denotes the position of those ones (say in increasing order, it doesn't matter actually). We have to calculate.
