Consider the experiment of tossing three coins.

What is the probability of getting anything but one head and two tails?

I need help on how to figure this out please!

That's what I tried to type in for my answer it was wrong. I tried .375 and then I tried it rounded off 38 % both were wrong.

But your question says "What is the probability of getting anything **but one head and two tails**?"

So, the probability for ANY OTHER combination would be:

1 - 3/8 =5/8 !!!

So I found that 5/8 works for the answer but I had to put it like this 62.5 %.
