5. Suppose a lab rat enters the box with four openings as shown. If cach decision about the direction is made at random, create
a simulation to determine the probability that the lab rat will
leave the box before going through 5 intersections.

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
