I have two cubes such that, on each cube, three faces are painted red and three faces are painted white. If I roll each of the cubes once, what is the probability that they will land such that there are two red faces up?

The probability that the first cube has red facing upwards is  3/6  =  1/2.

Similarly, the probability that the second cube has red facing upwards is  3/6  =  1/2.

 

The probability that both cubes have red facing upwards is  1/2 x 1/2  =  1/4.
