Probability of the students having brown hair = 0.6
Probability of the students having brown eyes = 0.3
Probability of the students having both brown hair and brown eyes = 0.1
Step-by-step explanation:
Step 1 :
Given,
Percentage of the students having brown hair = 60%
Percentage of the students having brown eyes = 30%
Percentage of the students having both brown hair and brown eyes = 10%
We need to obtain the probability of each separately, when a student is chosen randomly
Step 2 :
The probability of each event happening given its percentage, can be obtained by dividing the corresponding percentage by 100.
Hence we have,
Probability of the students who have brown hair = = 0.6
Probability of the students who have brown eyes = = 0.3
Probability of the students who has both brown hair and eyes = = 0.1
Step 3 :
Answer :
Probability of the students who have brown hair = 0.6
Probability of the students who have brown eyes = 0.3
Probability of the students who has both brown hair and eyes = 0.1
