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.
