Answer to Problem 35E
The probability that a student does not have brown eyes provided that the student does not have brown hair is
Explanation of Solution
Given information:
Percentage of students with brown hair is
Formula used:
Probability of an event Eis
Given an event Q , the conditional probability of event A is
Calculation:
Consider the provided information thatPercentage of students with brown hair is
Let A be an event that student does not have brown eyes and B be an event student does not have brown hair.
Recall that probability of an event Eis
Probability that student does not have brown hair,
Now,
Probability that student does not have brown eyes,
Recall that given an event Q , the conditional probability of event A is
The probability that a student does not have brown eyes provided that the student does not have brown hair.
Thus, the probability that a student does not have brown eyes provided that the student does not have brown hair is
