Answer #1

A weakly dominant strategy refers to that strategy that gives at least same utility for all agents and strictly greater for a particular strategy.

(a)

Following restrictions are put on a, b, c that makes (T, L) a weakly dominant strategy.

a >= 3

b <= 1

and c <=0

(b)

After using Hit and Trial, following values of a, b, c makes the (T, L) as Nash Equilibrium

a= 4

b = 0

c = -1

L R
T (4, 1) *# (2, 0)#
B (3, 0)* (2, -1)#

(T,L) is the Pure Strategy Nash Equilibrium in above game
