4 Jimmy is drunk again and is walking randomly, such that every second he steps to our left (towards the edge of the cliff) or our right (away from the edge) with the following probabilities: P(step to our left) = .3 P(step to our right) = .7 Assume that the steps are independent trials. Jimmy starts at point 2. If he reaches point 0, he falls off the cliff. If he reaches point 4, he stops walking, sits down on the chair, and sobers up. - 0.3 0.7 2 3
