Final answer:
70 percent of the beings surveyed on planet Pisquet preferred joogh juices, calculated by dividing the number of beings who preferred joogh juices (21) by the total number of beings surveyed (30), then multiplying by 100%.
Step-by-step explanation:
To calculate the percentage of beings on planet Pisquet that preferred joogh juices, we can use the formula for percentage:
Percentage = (Number of beings preferring joogh juices / Total number of beings surveyed) × 100%
Given that 21 out of 30 beings preferred joogh juices, the calculation would be:
Percentage = (21 / 30) × 100% = 70%
Therefore, 70 percent of the beings surveyed on planet Pisquet preferred joogh juices.
