Question

Quizplus · Accepted Answer

The probability of being a girl is 20/25 = 4/5. The probability of having brown hair is 10/25 = 2/5. The probability of being a girl and having brown hair is 8/25. Since the probability of being a girl and having brown hair is not equal to the product of the probability of being a girl and the probability of having brown hair, the events are not independent.
