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

    Specs:
    - 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!
