Answer:   8

=====================================================

Explanation:

According to the table, 10 people have brown eyes. This is out of 1+10+1+1+7 = 20 people total. So 10/20 = 0.50 = 50% of the group has brown eyes.

If this trend holds up, then we expect 50% of the next group of 16 people also have brown eyes.

50% of 16 = 0.50*16 = 8

We expect 8 people to have brown eyes in this next group. This is of course assuming that the first group is unbiased and represents the population (or is close enough).
