To determine the expected number of black-haired individuals among the next 16 people to take their seats, we first need to establish the proportion of black-haired individuals in the current group.
From the information provided:
- Total people already seated: 2 (black-haired) + 2 (not black-haired) = 4 people
- Proportion of black-haired individuals = Number of black-haired people / Total number of people = 2 / 4 = 0.5
Now, we can use this proportion to estimate how many of the next 16 individuals are expected to be black-haired.
Expected number of black-haired people among the next 16 = Proportion of black-haired individuals × Number of people
Calculating that:
Expected number of black-haired people = 0.5 × 16 = 8
Therefore, you should expect about **8** of the next 16 people to take their seats to be black-haired.
