Given :
Number of yellow cubes = 8
Number of blue cubes = 7
Number of red cubes = 5
Total = 8 + 7 + 5 = 20
Here, we have to calculate the probability of not selecting blue or red cube. So, that means we have to calculate the probability for selecting yellow cube.
We know,
Probability = favorable outcome/Total outcome
Probability = 8/20
= 2/5 or 0.40
Thus, probability of not selecting a blue or red cube is 2/5 or 0.40
