In a two asset portfolio, the expected return of the second asset, b, can be calculated as if e(rp) is the expected return of the portfolio, e(ra) is the expected return of stock a, e(rb) is the expected return of stock b, wa is the weight of stock a, and wb is the weight of stock b. group of answer choices e(rb) = [e(rp) + wa*e(ra)]*wb e(rb) = [e(rp) + wa*e(ra)]/wb e(rb) = [e(rp) – wa*e(ra)]*wb e(rb) = [e(rp) – wa*e(ra)]/wb e(rb) = [e(rp) – wa*e(ra)]^wb
