Question
The table shows the results of randomly selecting a colored cube from a bag 80 times. The cube was returned to the bag after each selection.
Blue Orange Purple Red Yellow
Number of Times Selected 14 8 16 24 18
Based on these results, what is the expected probability of randomly selecting a red cube from the bag in one attempt?
Responses
A 0.240.24
B 0.200.20
C 0.040.04
D 0.30
To find the expected probability of randomly selecting a red cube from the bag in one attempt, we need to calculate the total number of times the red cube was selected and divide it by the total number of selections:
Total number of selections = 80
Number of times red cube was selected = 24
Expected probability = Number of times red cube was selected / Total number of selections
Expected probability = 24 / 80
Expected probability = 0.30
Therefore, the answer is D) 0.30.
