Hi, I have to write a code to flip 3 coins a given number of times. Someone can help me? Thank you

may make a code about probability of appearing head or tail in all flip

Use inputdlg() to ask the user for the number of flips, and randi() to do the flips. Here's a start:
% Ask user for one integer number.
defaultValue = 5;
titleBar = 'Enter number of flips';
userPrompt = 'Enter flips';
caUserInput = inputdlg(userPrompt, titleBar, 1, {num2str(defaultValue)});
if isempty(caUserInput),return,end; % Bail out if they clicked Cancel.
% Round to nearest integer in case they entered a floating point number.
numFlips = round(str2double(cell2mat(caUserInput)));
% Check for a valid integer.
if isnan(numFlips)
% They didn't enter a number.
% They clicked Cancel, or entered a character, symbols, or something else not allowed.
numFlips = defaultValue;
message = sprintf('I said it had to be an integer.\nI will use %d and continue.', numFlips);
uiwait(warndlg(message));
end
% Now do the flips of the 3 coins.
numCoins = 3;
fprintf('1 = heads, 2 = tails\n');
for flip = 1 : numFlips
fprintf('\nHere is flip #%d\n', flip);
coinStates = randi(2, 1, numCoins)
end

Hi Francesco,
My functions Flip a Coin or Roll a Dice with Matlab is exactly what you want. You can try them.
All best,
