Coin Flipper

The game is simple. Every time you click on toss coins you get 4 coin tosses. Your goal is to try to answer these two questions:

1 - if you do 30 tosses (4 coins each toss ) how many times will you get all clown face, meaning that the 4 coins show a clown face?

2- what is the average number of clown faces in a 4 coin toss?

The second question requires you to play with it a little bit more closely. For each toss count the number of clown faces. It will be any where from 0 to 4. 

To get probability of 0, just divide the number of times you got zero by the total number of tosses. And the same 1, 2, 3 and 4.

The average is = (probability of zero) * zero + (probability of 1) * 1 + same for 2,3, and 4.

Hope you had fun checking out this little game I made!!
