a).Random walk on the line: a drunk walker takes step left or right with probability 1/2. Assuming that one step if 3 ft and he takes a step every second, what is the probability that he will be at a distance 100 ft or more from the place he started after one hour? Use CLT to assess the probability.

b). Random walk on the plane: a drunk walker takes a step left, right, up, or down with probability 1/4. Assuming that one step is 3ft and he takes a step every second, what is the probability that he will stay within the square + 100ft centered on the place he started after one hour? Use CLT to assess the probability.
