Suppose, instead, that the individual is offered the choice between asset C and asset D. Asset pays $1,500 with probability 0.25 oz $100 With probability 0.75, while asset D pays $2.000 with probability 0.2 or $100 with probability 0.8. If asset D is chosen, show that the individual's preferences violate the independence axiom
