PLease explain......
f
: [−1 1]- R f (x) = ((x\2) +1 ) * e^(x-1) .
Please give me some guidlance on the following problem :
LetX be a random variable such that its values lie in the interval [−1 1] and consider the function
f: [−1 1]- R f (x) = ((x\2) +1 ) * e^(x-1) .
a) Prove that f can be the probability density of X.
b) Compute the expected value of X.
Many thanks,
Let X be a random variable such that its values lie in the interval [−1 1] and consider the function
f: [-1,1] in the set of real numbers and we have
f(x) = ((x\2) +1 ) * e^(x-1)
a) Prove that f can be the probability density of X.
b) Compute the expected value of X.
Hope now it's clear for you Unfortunately it's not for me . Please give me some guidance.
