If we assume Var(x) is not = 0, show that p(Y, 7Y+3) = 1.
To solve this question it is my understanding that we use the correlation formula,
ρ(X, Y ) = Cov(X, Y) / sqrt[Var(X)] sqrt[Var(Y)].
The theory behind it makes sense but I can't figure out how to show the work here. Thanks for your help!1 AnswerMathematics10 months ago
An interviewer is given a list of potential people she can interview. She needs five interviews to complete her assignment. Suppose that each person agrees independently to be interviewed with probability 2/3. What
is the probability she can complete her assignment if the list has 8 names?
I'm stuck on this problem because there is a chance that the interviewer will finish the interviews before getting to 8 names. Anyone know how to solve this?1 AnswerMathematics10 months ago
