Jquerry chosen dropdown dissable when checkbox is enabled

Jquerry chosen dropdown dissable when checkbox is enabled

Greetings

I'm  really new in jquerry and i'm having difficulties figuring out how to disable a drop down list by id when a checkbox is checked. 

The logic would look like this. 

1) If a checkbox is enabled (checked) then disable drop down
2) If a checkbox is disabled (unchecked) then enable the drop down

The checkbox id for example is Trivial_Order and the Dropdown id is manager_search


I just can't figure out how to implement this checkbox logic in this code. 

Could anyone please help?
