I have some things that have a 7% chance of being blue, 10 of these things are put in a box. What is the percent chance that the box will have exactly one blue thing? Two blue things? and so on.. I have simulated this and came up with the following (all appx) 0 - 37% 1 - 37% 2 - 18% 3 - 5% 4 - 1.2% 5 - 0.12% What equations do I use to solve this exactly?
