Rolling Two Dice.pdf

In the attached document how would you write a command to generate two random numbers for two dice. Below is for one dice; so do you just change roll=randi statement, and put in 2,12 in place of 1,6?

rng('shuffle')
numRolls=input('Please enter how many rolls you would like to simulate:')
counts = zeros(1,6) 
for r = 1 : numRolls
  roll = randi([1 6],1)
  counts(roll) = counts(roll)+1
end

counts = (counts / numRolls)*100

Try this:

rng('shuffle')
numRolls=input('Please enter how many rolls you would like to simulate:')
counts = zeros(1, 12);
numDice = 2;
for r = 1 : numRolls
    roll = randi([1 6],1,numDice);
    theSum = sum(roll);
    counts(theSum) = counts(theSum) + 1;
end
counts = (counts / numRolls) * 100
