How do you use Simulink to create a pathway with a switch that splits into two based on probability (for eg, 0.4 of the time goes through port A and 0.6 of the time goes through port B)?

This seems to work for me (The uniform random number is set to a range of 0 to 1):

Thanks so much! Looking forward to trying it but this was exactly along the lines of what I was thinking. I’m trying to create a Markov chain model similar to what is possible with TreeAge Pro

I'm thinking that one way to implement this in a subsystem like this:

In this case, the enabled subsystems simply pass the signal straignt through. Signals A and B are defined outside, and the subsystem simply acts a a probabilistic switch between A and B.
You can create a mask for the subsystem and set the percentage threshold (i.e. the 0.4 value) in the mask.
