Hello, good day,

Here is a thread to go about.

The problem I faced is that no box has been specified please help.

Question.

The contents of two boxes are as follows; box A contains 3 red and 2 white balls, box B contains 2 red and 5 white balls. a box is selected at random, a ball is drawn and put into second box, and then a ball is drawn from the second box. Find the probability that both balls drawn are of the same colour.
