Okay then split the problem.
Once the coin is on the table there is a 50/50 chance of red and blue. But that is half the problem. We also need to actually pick a coin.
The red/blue coin can only be picked with the blue side up whereas the blue/blue coin can be picked with either side up. So the likelihood of the coin being the red/blue is 1/3 and the likelihood of it being the blue/blue coin is 2/3.
