There are 2 bags. Bag A contains 100 gold coins. The other bag B contains 50 gold coins and 25 silver coins.

Suppose John chose a bag and then picked 1 coin from within, the coin was a gold coin, what's the probability

that he picked bag A ?

The answer is 0.5833 using Bayes' Theorem.

Does anyone know how to calculate this?

**What if instead of picking only 1 coin, John picked 2 coins and both coins were gold coins. Now**

what's the probability that he picked bag A ?what's the probability that he picked bag A ?
