In Melissa's grade at school, 55 of the students are girls and 65 of the students have brown hair. There are 35
girls with brown hair. There are a total of 100 students in her grade. What is the probability that someone with
brown hair will also be female?
Round your answer to the nearest hundredth
The probability that someone with brown hair will also be female can be calculated using the formula for conditional probability:
P(female | brown hair) = P(female and brown hair) / P(brown hair)
Given:
P(female and brown hair) = 35
P(brown hair) = 65
Therefore, P(female | brown hair) = 35 / 65 ≈ 0.54
So, the probability that someone with brown hair will also be female is approximately 0.54 to the nearest hundredth.
