random fill check box/es

sorry for the dumb question first.  I don't even know if its possible.

if there any way to put a random check mark with the click of a button?  a click will provide check mark/s on the different check box/es...

for example..

I have 10 check boxes.  when i click on a button or 1 of the checkbox, it will put check marks on 1, 2, or 3 check marks in any of the 10 check boxes?

also, can i put a random but check mark on certain check box more frequent? check box 5, 6, and/or 7 gets most check mark??

I am sorry if i am not clear but I am trying to generate random check mark on my 10 check boxes automatically and favors check box #5,6, and/or 7.

Any help will be greatly appreciated.

Thank you!
