Question
A group of students voted on their favorite subject. 23 students enjoy Mathematics, 40 enjoyed English, 22 enjoyed Science, 10 enjoyed Hindi and 5 enjoyed History.
Read the above case study carefully and give the answer of the following questions.
1. What is the probability of selecting a student who enjoys Science?
2. What is the probability of selecting a student who enjoys Mathematics?
3. What is the probability of selecting a student who enjoys English?
Answer
Total no of students=23+40+22+10+5=100
We know that Probability of an event
=Number of favourable outcomes/ Total number of possible outcomes
1 - Probability of selecting a student who enjoys Science
⇒Students enjoyed Science/Total no of students =22/100=11/50
2- What is the probability of selecting a student who enjoys Mathematics?
⇒Students enjoyed Maths /Total no of students
=23/100
3-What is the probability of selecting a student who enjoys English?
⇒Students enjoyed English/Total no of students
=40/100=4/10=2/5
