I keep getting an error every time I try to do calculations with large numbers. I was wondering if there was another way to do these problems or a way to simplify them. As you can see, with smaller numbers I can put them into my calculator and get an answer:

If you flip a coin 50 times, what is the chance you will get 25 heads?

But if I do a problem like this, I get the "OVERFLOW" error on my calculator and I can't do it:If you flip a coin 100 times, what is the chance you will get 50 heads?

Is there another way to calculate the answer for the second problem so I don't get "OVERFLOW" in my calculator every time I try to do it?
