Number of Pets 0 1 2 3 4
Number of Students 8 4 5 10 3 The table above shows the number of pets kept by 30 students in a class.
If a student is picked at random from the class, what is the probability that he/she kept more than one pet?

Are you talking about one class?
To find the probability that a student kept more than one pet, we need to calculate the total number of students who kept more than one pet and divide it by the total number of students in the class.
Looking at the table, we can see that there are 8 students who kept 0 pets, 4 students who kept 1 pet, 5 students who kept 2 pets, 10 students who kept 3 pets, and 3 students who kept 4 pets.
To calculate the total number of students who kept more than one pet, we can add up the number of students who kept 2, 3, and 4 pets:
Total number of students who kept more than one pet = 5 + 10 + 3 = 18
Now, we can calculate the probability by dividing the total number of students who kept more than one pet by the total number of students in the class:
Probability = Number of students who kept more than one pet / Total number of students in the class
Probability = 18 / 30 = 0.6
Therefore, the probability that a student picked at random from the class kept more than one pet is 0.6 or 60%.
