We will calculate conditional probability.
There are two boxes, A and B, and each box contains a certain number of winning tickets
mixed in with losing tickets.
We will randomly select a box and draw one ticket from it.
Now, assuming you drew a winning ticket, let’s calculate the conditional probability that “you drew from Box A.”
Number of winning tickets in Box A
枚　　(Integers greater than or equal to 0)
The total number of bills in Box A
枚　　(Natural numbers)
Number of winning tickets in Box B
枚　　(Integers greater than or equal to 0)
The total number of bills in Box B
枚　　(Natural numbers)

Let x be the event of “drawing a winning ticket.”
Let y be the event of “selecting Box A.”
We calculate this using P(y) = P(x ∩ y) / P(x).
