Question

Fred the ant is on the real number line, and Fred is trying to get to the point O

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 e1 be expected number of steps Fred takes to get to 0 given that Fred starts at the point 1. Similarly, let e2 be expected number of steps Fred takes to get to 0 given that Fred starts at the point 2

Find e1 and e2.​

Answer 1

Use this approach to get your answer that's (e1,e2) = (2,4) if this help then your welcome

Explanation:

Answer 2

Use a recursive approach to get (e1,e2) = (2,4).
