The correct Answer is:
To solve the problem step by step, we will calculate the probability of two events: (i) a student liking cricket matches and (ii) a student disliking cricket matches. ### Step-by-Step Solution: 1. **Identify the total number of students surveyed:** \[ \text{Total number of students} = 300 \] 2. **Identify the number of students who like watching cricket matches:** \[ \text{Number of students who like cricket} = 186 \] 3. **Calculate the number of students who dislike watching cricket matches:** \[ \text{Number of students who dislike cricket} = \text{Total students} - \text{Students who like cricket} \] \[ = 300 - 186 = 114 \] 4. **Calculate the probability that a randomly chosen student likes watching cricket matches:** \[ P(\text{likes cricket}) = \frac{\text{Number of students who like cricket}}{\text{Total number of students}} \] \[ = \frac{186}{300} \] To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor (GCD), which is 6: \[ = \frac{186 \div 6}{300 \div 6} = \frac{31}{50} \] 5. **Calculate the probability that a randomly chosen student dislikes watching cricket matches:** \[ P(\text{dislikes cricket}) = \frac{\text{Number of students who dislike cricket}}{\text{Total number of students}} \] \[ = \frac{114}{300} \] Again, we simplify this fraction by dividing both the numerator and the denominator by their GCD, which is 6: \[ = \frac{114 \div 6}{300 \div 6} = \frac{19}{50} \] ### Final Answers: (i) The probability that the chosen student likes watching cricket match is \( \frac{31}{50} \). (ii) The probability that the chosen student dislikes watching cricket match is \( \frac{19}{50} \).
