Python help please write function to calculate E(y) and Var(y)

Only write Python

Write a function that uses independent random samples to simulate the following approximate counting formulas. Number the samples randomly 1 through n.

Y = the number of subsets that test positive. p = probability of infection

I wrote function to make n and k. please look at the code for n and k. It's given already

Now Just write below formula only E(y) and Var(y) in python for calculating variance and estimate

Again only calculate E(y) and Var(y)
