You can use the demperical distribution to manually input the probability of a token going through any of the outputs on the Decide activity. The demperical distribution uses a Global Table with two columns and a number of rows equal to all possible values (five in this case, so five rows). The first column is the probability that the associated value will be used and the second column is the value itself. So your Global Table will look like this:

And in the Delay activity, in the Send Token To field, you can choose Statistical Distribution from the dropdown menu and choose D Emperical. It'll end up looking like this once it's set up correctly:

Or you can just put the same code that is generated into the Send Token To field directly:
dempirical("DempericalTable", getstream(activity))Where "DempericalTable" should be replaced with the name of the Global Table you are using.
