Sagot :

Given:

The number of people for each eye color

Brown = 35, Blue = 4, Hazel = 10, green = 1

The likelihood of an event e occurring can be calculated using the formula:

[tex]P(an\text{ event e occuring\rparen = }\frac{number\text{ of required outcomes}}{Total\text{ number of possible outcomes}}[/tex]

So, we have

Total number of people = 50

Next, we find the likelihood for each event

The likelihood for Brown:

[tex]\begin{gathered} P(brown)\text{ = }\frac{35}{50} \\ =\text{ }\frac{7}{10}\text{ } \\ =\text{ 0.7 or 70\%} \end{gathered}[/tex]

The likelihood for Blue:

[tex]\begin{gathered} \text{P\lparen blue\rparen = }\frac{4}{50} \\ =\frac{2}{25}\text{ or 0.08 or 8\% } \end{gathered}[/tex]

The likelihood for Hazel:

[tex]\begin{gathered} P(hazel)\text{ = }\frac{10}{50} \\ =\text{ }\frac{1}{5} \end{gathered}[/tex]

The likelihood for green:

[tex]P(green)\text{ = }\frac{1}{50}[/tex]

Next, we step through the options and check which is correct

Option A:

The likelihood of blue or green :

[tex]\begin{gathered} =\text{ }\frac{2}{25}\text{ + }\frac{1}{50} \\ =\text{ }\frac{4}{50}\text{ + }\frac{1}{50} \\ =\frac{5}{50} \\ =\text{ }\frac{1}{10} \end{gathered}[/tex]

The likelihood of hazel eyes is greater than the likelihood of blue or green

Option B:

The likelihood of having a blue eyes is greater than the likelihood of having green eyes

Incorrect

Option C:

The likelihood of having a blue eyes is 4%

Incorrect

Option D:

The likelihood of having a brown eyes is 70%

This is correct
