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%.
