Tpt probably
Bag A chosen * red * black + Bag B chosen * red * black=1/3*(4/10 times 6/9 times 2)+(Similarly casework for bag B)
how do u know its red first then black?
We don't that's why there a "times 2" at the end of the first case.
but wouldnt the probability change if its black then red
The numerical value for both would be equal.
