The expected rate of return for the second investment is (.45 * .2) + (.55 * -1) = -46%; The expected rate of return for the third investment is (.8 * .5) + (.2 * -1) = 20%; These calculations show that in our scenario the third investment is expected to be the most profitable of the three. The second one even has a negative ROR.
