How would I create a item randomizer?

[sneekyo]

My idea is to have a vending machine. The player can hit a UI button and randomly an item will fall out of the machine for the player to pick up.

I want to have a 10% chance of a secret weapon, and then 30% chance for 3 other items.

I'm new to playmaker and I'm wondering how this would be possible.

Any help is greatly appreciated.

Use Send Random Event, set weights (0.1, 0.3, 0.3, 0.3) and voila.
