Question 2 Consider three choices A, B, C. Choice A gives $40 with probability 1/4 and $80 with probability 3/4. Choice B gives $70 with certainty. Choice C gives $56 with probability 1/4 and $80 with probability 3/4. (a) [2 points] Determine if a risk averse individual (i) prefers A over B, or (ii) prefers B over A, or (iii) more information on the individual's risk attitude is needed to compare A,B for the individual. (b) [2 points] Determine if a risk averse individual (i) prefers A over C, or (ii) prefers C over A, or (iii) more information on the individual's risk attitude is needed to compare A,C for the individual. (0) [2 points] Determine if a risk averse individual (i) prefers B over C, or (ii) prefers C over B, or (iii) more information on the individual's risk attitude is needed to compare B,C for the individual
