A survey was done about the pets owned by students. The probabilities of students owning specific pets are listed above.
If there are 4 4 dogs owned, how many pets are owned in total?
Solution
To find the total number of pets owned, we need to understand that the numbers given are probabilities. The probability of an event is calculated by dividing the number of ways an event can occur by the total number of outcomes.
In this case, the probability of a student owning a dog is 8/44 (from the given data).
If there are 4 dogs owned, we can set up the equation:
(4 dogs / total pets) = 8/44
Solving for total pets gives us:
total pets = 4 dogs * (44/8) = 22 pets
So, if there are 4 dogs owned, there are 22 pets owned in total.
