## Solution

Dear visitors and friends of the site. Thank you for your solutions. Sadly, this time no correct answers have been submitted.

Here is the solution:

We have a line of objects ( 10 postcards and 4 barriers that separate the mailboxes). Thus we need to count the number of possibilities to find spaces for 4 barriers, in other words - to choose 4 objects among 14 ( the order is not important).Hence the solution is the number of combinations 14C4.

Thank you again and have a great summer.

The next problem appears in September.
