Say I have two unfair coins, I ask someone to toss coin A 100 times and coin B 50 times and tell me the results (for example: coin A was head 20 times and tails 80 times while B was head 40 times and tails 10 times)
Now someone picks evenly coin A or B, tosses it as well and tells the result. How do I calculate the probability that coin A was tossed vs the probability that B was tossed?
