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.

P(more than one pet)=Number of students with more than one petTotal number of studentsP(\text{more than one pet}) = \frac{\text{Number of students with more than one pet}}{\text{Total number of students}}
P(more than one pet)=530P(\text{more than one pet}) = \frac{5}{30}
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 16\frac{1}{6}.
