Answer:
23% of student will have red hair given that the student has green eyes.
Step-by-step explanation:
We are given the following in the question:
Percentage of students that have green eyes = 65%
[tex]P(G) =0.65[/tex]
Percentage of students that have red hairs = 25%
[tex]P(R) =0.25[/tex]
Percentage of students that have green eyes and red hairs = 15%
[tex]P(G\cap R) =0.15[/tex]
We have to find the conditional probability of randomly selected student that will have red hair given that the student has green eyes.
[tex]P(R|G) = \dfrac{P(R\cap G)}{P(G)}[/tex]
Putting values, we get,
[tex]P(R|G)=\dfrac{0.15}{0.65} = 0.2307\approx 23\%[/tex]
Thus, 23% of student will have red hair given that the student has green eyes.
