Define the following two events: A = a bridge has been inspected in the last 6 months and B = a bridge is more than 25 years old. What does the intersection of A & B represent? A bridge has been inspected in the last 6 months or is more than 35 years old but not both. A bridge has not been inspected in the last 6 months but is more than 25 years old. A bridge has been inspected in the last 6 months or is more than 25 years old or both. A bridge is not more than 25 years old but has been inspected in the last 6 months.
