    Could someone please help me finish my MatLab script for the following specifications of this scenario:

    - 2 players flip a fair coin
    - Bet sizes are equal

    I'm trying to plot the distribution of the length of winning streaks for the game with numeric MatLab. Below is what I have so far:

    % Arbitrary Scenario:
    % Total of 10 coin tosses
    % Player 1 (P1) bets on heads for each toss; Player 2 (P2) bets on tails
    % for each toss

    n = 10; % Coin is tossed 10 times
    t=rand(1,n)<0.5; % Random generation of a vector of 10 0's or 1's
    x=sum(t); % Count the number of heads (Amt of P1 wins)
    y=n-x; % Count the number of tails (Amt of P2 wins)

    Now all I want to do is plot the distribution for x and y.
    Did I approach my problem correctly or did I miss anything? How would you guys go about plotting this distribution of length of winning streaks?

    Many thx in advance!

    Where in your work have you done anything having anything to do with winning streaks?
