bool

    // usages
    randBox.bool()
    randBox.bool({ likelihood: 30 })

Return a random boolean value (true or false).

randBox.bool();
=> true

The default likelihood of success (returning true) is 50%. Can optionally specify the likelihood in percent:

randBox.bool({likelihood: 30});
=> false

In this case only a 30% likelihood of true, and a 70% likelihood of false.
