1. Problem Description
The table shows the number of pets kept by 30 students in a class. We need to find the probability that a randomly picked student kept more than one pet.
2. Solution Steps
From the table, we have the following information:
- 8 students have 0 pets.
- 4 students have 1 pet.
- 5 students have 2 pets.
The total number of students is
3
0. We are given that in the problem.
The number of students who have more than one pet is the number of students who have 2 pets, which is
5. The probability of a student having more than one pet is the number of students with more than one pet divided by the total number of students.
We can simplify this fraction by dividing both the numerator and the denominator by
5. $P(\text{more than one pet}) = \frac{5 \div 5}{30 \div 5} = \frac{1}{6}$
3. Final Answer
The probability that a student kept more than one pet is .
