In an apartment building with 60 tenants, 15 people own dogs, 20 own cats, 6 own fish, and 19 have no pets. Based on this data, for each number select the probability it represents.
15/60 owns dogs
20/60 owns cats
6/60 owns fishes
19/60 has no pet
To determine the probability for each number, we divide the count of each event by the total number of tenants.
1. Probability of owning a dog:
Given that 15 people own dogs, and there are a total of 60 tenants, the probability of owning a dog is 15/60 = 1/4.
2. Probability of owning a cat:
Given that 20 people own cats, and there are a total of 60 tenants, the probability of owning a cat is 20/60 = 1/3.
3. Probability of owning fish:
Given that 6 people own fish, and there are a total of 60 tenants, the probability of owning fish is 6/60 = 1/10.
4. Probability of having no pets:
Given that 19 people have no pets, and there are a total of 60 tenants, the probability of having no pets is 19/60.
Please note that the probabilities for owning a dog, cat, and fish are expressed as fractions, while the probability of having no pets is represented as a fraction but can also be expressed as a decimal or a percentage.
To find the probabilities for each number, we need to divide the number of people who own each type of pet by the total number of tenants.
Let's calculate the probabilities for each number:
1. Probability of owning a dog:
Number of people who own dogs = 15
Total number of tenants = 60
Probability of owning a dog = Number of people who own dogs / Total number of tenants = 15 / 60 = 0.25
2. Probability of owning a cat:
Number of people who own cats = 20
Total number of tenants = 60
Probability of owning a cat = Number of people who own cats / Total number of tenants = 20 / 60 = 0.33
3. Probability of owning fish:
Number of people who own fish = 6
Total number of tenants = 60
Probability of owning fish = Number of people who own fish / Total number of tenants = 6 / 60 = 0.1
4. Probability of having no pets:
Number of people with no pets = 19
Total number of tenants = 60
Probability of having no pets = Number of people with no pets / Total number of tenants = 19 / 60 = 0.32
Therefore, the probabilities for each number are as follows:
1. Probability of owning a dog: 0.25
2. Probability of owning a cat: 0.33
3. Probability of owning fish: 0.1
4. Probability of having no pets: 0.32
