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.
To find the expected probability of randomly selecting a red cube from the bag in one attempt, we need to calculate the probability.
In this case, the total number of cubes selected is given as 80, and the number of times a red cube was selected is given as 24.
So, the probability of selecting a red cube in one attempt can be calculated as:
Probability = (Number of red cubes selected) / (Total number of cubes selected)
Probability = 24/80 = 0.30
Therefore, the expected probability of randomly selecting a red cube from the bag in one attempt is 0.30.
So, the correct answer is option C: 0.30.
