Can you please do it by matlab both two questions

In a one-dimensional random walk. the position x of a walker is computed by where s is a random number. Write a program that calculator the number of steps required for the walker to reach a boundary x = plusminus B. Use MATLAB's built-in function random (1, 1) to calculate x. Run the program 100 times (by using a loop and calculate the average number of steps when B = 10. The sierpinski triangle can be implemented in MATLAB by plotting points iteratively according to one of the following three rules that are selected randomly with equal probability. Rule 1:x_a - 1 = 0.5x_in Y_a - 1 = 0.5 Y_n Rule 2: X_a - 1 = 0..5 x_n + 0.25, y_a - 1 = 0.5 y_a + (squareroot 3)/4 Rule 3: X_a - 1= 0.5 x_n + o.5, y_a - 1= 0.5 y_n Write a program in a script file that calculates the x and y vectors and then plots y verses x as individual points (Use plot (x, y, ).Start with X_1 = 0 and Y_1 = 0.Run the program four times with 10, 100, 1,000.and 10,000 iterations
