Question

The people who responded to a survey reported that they had either brown, green, blue, or hazel eyes. The results of the survey are shown in the table. A 2-column table has 4 rows. The first column is labeled Eye Color with entries brown, green, blue, hazel. The second column is labeled Number of People with entries 20, 6, 17, 7. What is the probability that a person chosen at random from this group has brown or green eyes?

Answer 1

It is 26/50 or if you want the simplified version it's 13/25 or 54%.

Explanation:

First, you have to calculate the number of people there are all together in the group. You do that by adding together the amounts of people in the groups. You have 20 brown-eyed people, 6 green-eyed people, 17 blue-eyed people, and 7 hazel-eyed people which means you have 50 people altogether. Then you have to calculate the amount of brown or green-eyed people there are which gives you 26 people. Finally, you have to put the amount of brown and green-eyed people over the overall population and you get 26/50 which also equals 54 percent.
