**Exercise Problem: Probability and Cardio Activities**

The table below represents a set of 88 cardio exercises categorized by activity type and duration. Your task is to calculate the probability of selecting a particular exercise that matches a specific description. Be sure to round your answers to 3 decimal places or present them as a percentage with one digit past the decimal. Don't forget to show your work!

|             | Walk | Skate | Bike | Total |
|-------------|------|-------|------|-------|
| **Short**   | 8    | 3     | 22   | 33    |
| **Medium**  | 7    | 15    | 18   | 40    |
| **Long**    | 2    | 4     | 9    | 15    |
| **Total**   | 17   | 22    | 49   | 88    |

**Questions:**

a. What is the probability that the cardio was a long bike ride?

b. What is the probability that the cardio was a walk?

c. What is the probability that the cardio involved skating or was of a short duration?

d. What is the probability that the cardio was for a medium or long duration?

e. What is the probability that the cardio was of a short duration or involved biking?

f. Given that the cardio was of a short duration, what is the probability that it involved walking?

g. Given that the cardio involved skating, what is the probability that it was for a medium duration?

**Instructions for Filling the Answers:**

- **Box a**: Calculate the probability by dividing the number of long bike rides by the total exercises.
- **Box b**: Determine the probability by dividing the total number of walks by the total exercises.
- **Box c**: Add the probabilities of skating and short exercises, ensuring no double-counting.
- **Box d**: Sum the probabilities of medium and long exercises.
- **Box e**: Sum probabilities of short exercises and biking.
- **Box f**: Determine conditional probability for walking given a short exercise.
- **Box g**: Find conditional probability for a medium duration given the exercise involved skating.

Compute these probabilities based on the counts provided in the table above to obtain accurate results.
