I have 7 pictures and 3 envelops. The pictures are randomly distributed into the 3 envelops. What is the probability that we have at least one empty envelop?

It's been 20 years so I'm a little fuzzy.  I know there is a factorial involved.

I think it depends on what they are pictures of.

Yes I know there are factorials involved. It's basically the number of combinations with at least one empty envelop over the total possible number of combinations.

7-0-0, 0-7-0, 0-0-7
6-1-0, 6-0-1, 0-6-1
etc

I found a formula but it gave me an answer like 58% so I must be doing something wrong.

Okay how about this, I will send $5 to the first person that gives me a solution with the equations and formulas. I can pay by PayPal or transfer to your PokerStars account.

The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics. The answer to your question is zero.

The answer is zero because you already said they are distributed to all 3 envelopes... so they all have to have at least 1 picture in them?

PS: You are close to getting the $5. Unless someone beats you to it.

Come on, doesn't $5 mean a unit to some covers posters? It's free untaxable money for a bit of work.
