Consider particle “P” having random walk in 1-D, Let N steps of equal length be taken along a line. Let be the probability of taking a step to the right, the probability of taking a step to the left, “a” the number of steps taken to the right, and “b” the number of steps taken to the left. Write a MATLAB that calculates and plot the following parameters:

Total distance covered by a molecule from the initial point.

Total distance covered to the right.

Total distance covered to the left.

Expected Value of Number of steps towards right.
