Answer :
First, let's analyze the probabilities based on the number of cubes in the bag:
- There are 3 blue cubes, 8 red cubes, and 9 green cubes in the bag.
- The total number of cubes in the bag is 3 + 8 + 9 = 20 cubes.
Now, let's evaluate the given options:
A) Pull a blue cube 15 times:
- Probability of pulling a blue cube = Number of blue cubes / Total number of cubes = 3 / 20 = 0.15 or 15%
- The probability of pulling a blue cube is 15%, so option A is likely.
B) Pull more than two times as many red cubes as blue cubes:
- Number of red cubes = 8
- Number of blue cubes = 3
- More than two times the number of red cubes compared to blue cubes would be 2 * 3 = 6.
- Since 8 is more than 6, option B is likely.
C) Pull a red cube 40 times:
- Probability of pulling a red cube = Number of red cubes / Total number of cubes = 8 / 20 = 0.4 or 40%
- The probability of pulling a red cube is 40%, so option C is likely.
D) Pull a green cube 45 times:
- Probability of pulling a green cube = Number of green cubes / Total number of cubes = 9 / 20 = 0.45 or 45%
- The probability of pulling a green cube is 45%, so option D is likely.
E) Pull 50 blue cubes:
- Since there are only 3 blue cubes in the bag and you are drawing with replacement, it is highly unlikely to pull 50 blue cubes in 100 draws. Therefore, option E is unlikely.
In conclusion, based on the probabilities calculated, options A, B, C, and D are likely occurrences while option E is unlikely.
