The table shows the results of randomly selecting a colored cube from bag 80 times the cube was returned to the bag after each selection
Blue 14
Orange eight
Purple 16
Red 24
Yellow 18
Based on the results was the expected probability of randomly selecting a red cube from the bag
The expected probability of randomly selecting a red cube from the bag can be calculated by finding the relative frequency of red cubes in the sample.
Relative frequency of red cubes = Number of red cubes selected / Total number of selections
Relative frequency of red cubes = 24 / 80
Relative frequency of red cubes = 0.3
Therefore, the expected probability of randomly selecting a red cube from the bag is 0.3, or 30%.
Provided answers are
.24
.20
.04
.30
Based on the given results in the table, the probability of randomly selecting a red cube can be calculated as follows:
Total number of selections = 80
Number of red cubes selected = 24
Probability of selecting a red cube = Number of red cubes selected / Total number of selections
Probability of selecting a red cube = 24 / 80
Probability of selecting a red cube = 0.30
Therefore, the correct answer is 0.30, which is equivalent to 30%.
