You are managing an admission system for an amusement park. The park has a rule that only adults (18 years or older) or children accompanied by adults are allowed to enter. You have four people: Bob, Alice, John, and Mike.

• Use comparison operators and logical operators to determine if the admission criteria are met.
• Check if Bob and John can enter the park together. Store the result in the variable can_bob_and_john_enter.
• Check if Alice OR Mike can enter the park individually. Store the result in the variable can_alice_or_mike_enter.
• Check if Bob, Alice, and John can all enter the park together. Store the result in the variable can_bob_alice_john_enter.
