Nadia has 5 red cubes, 3 blue cubes, 8 yellow cubes, and 4 black cubes. She records the color cube she pulls from the bag and puts the cube back in the bag 14 times. The table below shows the frequency she pulled each color.
What are the experimental and theoretical probability of pulling a blue cube out of the bag? Enter your answer as a decimal rounded to the nearest hundredth (2 places after the decimal).
When entering responses, remember to include the ZERO before the decimal if necessary. For example, if the answer is 0.47, you must enter the zero for the answer to be counted correctly.

Theoretical P(blue) = Number of blue cubes / Total number of cubes
Theoretical P(blue) = 3 / (5 + 3 + 8 + 4)
Theoretical P(blue) = 3 / 20
Theoretical P(blue) = 0.15
Experimental P(blue) = Number of times a blue cube was pulled / Total number of pulls
Experimental P(blue) = 3 / 14
Experimental P(blue) = 0.21
Therefore,
Theoretical P(blue) = 0.15
Experimental P(blue) = 0.21
