Question
Each group of students receive a bag that has 8 red cubes, and 10 blue cubes each group makes 50 pulls with the results shown below. If the group were to continue the experiment and make 1, pulls, what would you expect to be the experimental of pulling a blue cube?

To determine the expected proportion of pulling a blue cube based on the results from the experiment, you first need to find the total number of pulls and the number of blue cubes pulled.
You mentioned that each group makes 50 pulls. Without the actual results of the number of blue cubes pulled from these 50 pulls, I can only guide you on how to calculate the expected proportion:
1. **Total Cubes**: In total, there are 8 red cubes and 10 blue cubes. Therefore, the total number of cubes is:
\[
8 + 10 = 18
\]
2. **Proportion of Blue Cubes**: The proportion of blue cubes in the bag is:
\[
\text{Proportion of Blue} = \frac{\text{Number of Blue Cubes}}{\text{Total Number of Cubes}} = \frac{10}{18} = \frac{5}{9}
\]
3. **Expected Pulls**: If the group continues the experiment and makes an additional 1,000 pulls, you can use the proportion of blue cubes to find the expected number of blue cubes pulled in those 1,000 additional pulls:
\[
\text{Expected Blue Cubes in 1000 Pulls} = 1000 \times \text{Proportion of Blue} = 1000 \times \frac{5}{9} \approx 555.56
\]
So, in those 1,000 additional pulls, you would expect to pull approximately 556 blue cubes (if rounding to the nearest whole number is required).
Overall, the expected fraction of pulling a blue cube in the entire experiment would still align with the original proportion of blue cubes from the bag, which is approximately 0.555 or 55.6%.
