Is there a method that returns true with the specified probability in Ruby?

It's just as the title says.
For the time being, we are working on the following items.

def hoge(n)
  # Generate an array with a true pair false of n to 100-n and randomly select one
  ([true]*n + [false]*(100-n)) .sample
end

If not, I would appreciate it if you could advise me on the method.
