Hello,

Let's say you shuffle a deck of cards and deal the first 3 cards face up. What are the odds of it being three 7's?

1 in...?

Thanks for the help

How many cards are in the deck?

How many 7's are in the deck?

What then is the probability of the first card being a 7?

Assuming that the first card is a 7, how many cards remain in the deck? How many of them are 7's?

What then is the probability of the second card being a 7?

And so forth.

If you get stuck, please reply showing your thoughts and efforts so far, so we can see where things are going sideways. Thank you! ;)
