In a study, a family involved may have only a car or only a bike or may have both. The probability that a family has a car, has a bike, or has both a car and a bike is equal to 0.61, 0.25, and 0.08 respectively. If we randomly choose a family, calculate the following probabilities:
- The probability that the family does not have a car.
- The probability that the family has at least one of them.
