What is Probability?
The probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The table of the number of people and the colour of their eyes colour is given as,
Colour of Eyes   Number of People
Brown                20
Green                6
Blue                 17
Hazel                7
According to the table, the total number of people who participated in the survey is 50. Therefore, the probability that a person chosen at random from this group has brown or green eyes can be written as,
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
[tex]\rm Probability=\dfrac{\text{Number of people with brown and green eyes}}{\text{Total number of people who participated in the survey}}[/tex]
[tex]\rm Probability=\dfrac{20+6}{50}=\dfrac{26}{50} = 0.52[/tex]
Hence, the probability that a person chosen at random from this group has brown or green eyes is 0.52.
