We have a cube with 4 blue faces and 2 red faces. What's the probability that if we color the faces randomly, then the red faces will be adjacent?

Color any face red

 

We have a choice of any of the remaining five faces to be red

 

But  only the oppsite face painted red will  not be adjacent

 

So....

 

P ( two adjacent red faces) =  4/5
