I don't know how to solve this:

Problem A Suppose that y; ~ Bernoulli(p(r;8)). Suppose y's are independent. p : R > 0, 1 is a generic function which takes values in [0,1]. 1. Compute the likelihood function for 8, for general function p 2. Suppose that p(t) = exp(t)/(1 + exp(t)). How does your answer to the previous question simplifies? 3. With p as in question 2, What optimization problem does the mle of B solve
