High School Math Tutor Job
I have a problem with probability:
I have 19 options, and 12 events for these options to be picked. If an option is picked, it is not depleted from the pool, so during the next event, the same option may be picked again.
I wanted to know:
A) the chance of getting any option twice
B) the chance of one specific option getting chosen twice
If I could get a simple explanation for how to solve this, so that I could replicate it further for triples, quadruples, etc. or for future problems, that would be much appreciated.
