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?

Step-by-step explanation:

Given

Required

Determine the probability of Brown or Green eyes

First, the total number of respondents have to be calculated;

The events described above is a mutually exclusive event and as such, the required probability will be calculated by;

Calculating P(Brown)

Substitute 20 for n(Brown) and 50 for Total

Calculating P(Green)

Substitute 6 for n(Green) and 50 for Total

So;

Take LCM

Divide the numerator and denominator by 2

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.
