16 out of 64 cars in a car park are toyota models. what is the probability that a car chosen at random is not a toyota model?
There are a couple of ways to approach this problem, but one common method is to use the complement rule:
- The complement of an event A is the event "not A", which consists of all outcomes that are not in A.
- The probability of not A is equal to 1 minus the probability of A.
Using this rule, we can first find the probability of selecting a Toyota model, and then subtract it from 1 to get the probability of selecting a non-Toyota model:
- Probability of Toyota = 16/64 = 0.25
- Probability of non-Toyota = 1 - 0.25 = 0.75
Therefore, the probability that a car chosen at random is not a Toyota model is 0.75 or 75%.
To find the probability that a randomly chosen car is not a Toyota model, we need to determine the number of cars that are not Toyota models and divide it by the total number of cars in the car park.
Given that there are 16 Toyota models out of 64 cars in the car park, the number of cars that are not Toyota models can be calculated by subtracting the number of Toyota models from the total number of cars:
Number of cars that are not Toyota models = Total number of cars - Number of Toyota models
= 64 - 16
= 48
Therefore, there are 48 cars that are not Toyota models.
To find the probability, we divide the number of cars that are not Toyota models by the total number of cars:
Probability that a car chosen at random is not a Toyota model = Number of cars that are not Toyota models / Total number of cars
= 48 / 64
= 0.75
Therefore, the probability that a car chosen at random is not a Toyota model is 0.75 or 75%.
To find the probability that a car chosen at random is not a Toyota model, we need to calculate the ratio of the number of cars that are not Toyota models to the total number of cars in the car park.
Given that there are 16 Toyota models out of 64 cars, we can subtract the number of Toyota models from the total number of cars to find the number of cars that are not Toyota models:
Total number of cars - Number of Toyota models = 64 - 16 = 48
So, there are 48 cars that are not Toyota models.
To calculate the probability, we divide the number of cars that are not Toyota models by the total number of cars:
Probability = Number of cars that are not Toyota models / Total number of cars
Probability = 48 / 64
Simplifying the fraction, we get:
Probability = 3 / 4
Therefore, the probability that a car chosen at random is not a Toyota model is 3/4 or 0.75.
