7 Question 3. [20 marks] The UTSC Marathon uses a lottery system to decide whether an applicant is allowed to participate. A runner is allowed to race if they win that year s lottery, or if they qualify based on the time in a previous race. The cutoffs are given below (if their time is below the given time for their category, they are automatically allowed entry). Men: 3 hours, Women: 2.3 hours, Under 18 years old: 3.5 hours, Over 60 years old: 3.7 hours No one under 15 or over 80 may participate regardless of lottery status or previous times (insurance reasons). In the space below, write a function to decide if an individual is allowed to participate in the race. You may not use any if statements, loops or any elements of Python we have not covered in lecture. Student #: Page 7 of 8 cont d...
