Hello. I need some help with these questions, I already handed in the assignment but did not get full marks. Thank you

(Picture 2 is a reference for the table)

Trust game Consider a version of the trust game in which player 1 (called A in the original study) can send an amount a out of an endowment of 10 to player 2 (or B), which is then tripled (3a). In this sequential game, player 2 may then send an amount b to player 1 but no more than the amount player 2 has received. Specifically, suppose 1 can send one of only three amounts, 2, 6, or 10, and player 2 can return one of three amounts, 3, 9, or 15. Thus, their payoffs are as follows: x, =10-a+b, de {L, M, H} = {2,6,10} x, =3a-b, be {L,M, H) = {3,9,15) whereby b 3a. 1. Calculate the payoffs of all feasible strategy pairs, {a, b} , and enter them in the table on the cover sheet. Suppose for problems 2 to 5 that players have egoistic preferences, specifically, u =x,i =1,2. 2. What is 2's best response (L, Mor H) to 1 choosing H? 3. What is 2's best response to 1 choosing M? 4. What is 2's best response to 1 choosing L?
