Attempting to simulate 4 coin tosses for a weighted coin, e.g. probability of heads = 0.9772 and tails = 0.0228
I want to list all the possible outcomes e.g;
HHHH = 0.9772^4
HHHT = 0.9772^3*0.0228 ...
Was wondering if there is a quicker way to list the outcomes as later on I will be simulating a larger amount of tosses.

Here's a way to compute heads or tails for a specified number of tosses and to list your strings of T's and H's.
% The probability of heads = 0.9772 and tails = 0.0228
pHeads = 0.9772;
numTosses = 200;
r = rand(1, numTosses) % Random numbers between 0 and 1
headTosses = r < pHeads
% Initialize character array to all tails
tosses = repmat('T', [1, numTosses])
% Assign the tosses that are heads to 'H'
tosses(headTosses) = 'H'

Thanks this helped a lot.
Do you know if there is any way to list all the possible outcomes and their probabilities?

Not off the top of my head, but for 200 coin tosses, there will be 2^200 possible combinations so there will not be enough time in the rest of this century to show them all to you. Why do you need to know that?
