To find the expected probability of randomly selecting a red cube in one attempt, we need to divide the number of red cubes by the total number of cubes.
From the table, we see that there are 24 red cubes out of a total of 80 cubes.
So, the expected probability of selecting a red cube in one attempt is:
24/80 = 0.3
Therefore, the correct answer is (C) 0.30.
