Ok, so here's the story. I'm playing as Portugal and after a war against Shawnee, Creek and that other one with my ally Spain a new CoT comes up. Seeing as its new it has 6 free slots and I have a 94.30 chance of getting in, so naturally seeing an easy way to get more money a send 5 merchants and only one gets in! I find this a little strange so basically is my chance of completing random?
