Fred the ant is on the real number line, and Fred is trying to get to the point 0
If Fred is at 1 then on the next step, Fred moves to either 0 or 2 with equal probability. If Fred is at 2 then on the next step, Fred always moves to 1
Let e_1 be expected number of steps Fred takes to get to 0 given that Fred starts at the point 1 Similarly, let e_2 be expected number of steps Fred takes to get to 0 given that Fred starts at the point 2
Determine the ordered pair (e_1,e_2)
I know that this question has already been posted but the answer was wrong
