Hello, I have a problem calculating the total number of options for the following scenarios.

Scenario 1) There are 15 different items, which can fit into 3 slots.
Scenario 2) There are another 4 different items and each of them can fit into 2 slots.

These items cannot repeat, so there cannot be a single item in all tree slots - always different items.

How many total combinations are there and what is the calculation, because I am getting 32 760, which is apparently not correct.

Can anyone give me a hand with it?

Thank you, Alex
 
Can you leave the slots empty? E.g., in 1) can you put all 15 items in the first slot?

Also, your answer 32760 -- is this for the Scenario 1) ?
