Write a program that determines the probability of tossing a coin 10 times and getting exactly 0, 1, 2, 3, etc. heads. This is the binomial probability distribution. Store the probability in an array. If you let r be 0, 1, 2,3, etc., then you would pass r to the function.

Use a for loop. The for loop will go from 0 to 10 inclusive. Use r as the number of successes. So r will go from 0 to 10. The probability of a success is .5, and also the probability of a failure is .5.

Print out in table form, column 1=r; goes 0 to 10, and then column 2; the probability of r.

Use 4 decimal places for the probability. You know if you get the correct answers because The sum of all the probabilities is 1.0, and all probabilities are in the range of 0 to 1 inclusive.

Excel also has a binomial probability function.

Store the factorials in an array.

Then when you need a factorial, like 4!, you just pull 4! from the array and use it in the calculation.

Once you are done calculating the probabilities, print out the probability array.
