Hi @sangagul1234ah@gmail.com,

Happy to help!

We know from the question stem that Fritz drives exactly twice but he drives on neither Tuesday nor Wednesday.

Rule 3 tells us that Fritz does not drive on Monday. However, Rule 2 tells us that no person drives on two consecutive days. As Fritz can only drive on Thursday, Friday, and Saturday and cannot drive on two consecutive days, then Fritz must drive Thursday and Saturday.

We also know that Jerry drives on at least Wednesday or Saturday. Since Fritz drives on Saturday, then Jerry must drive on Wednesday as well.

G H J F J F
M T W R F S

Notice that the above order meets all of our conditions:

1) Each of the four people drives on at least one day.
2) No person drives on two consecutive days.
3) Fritz does not drive on Monday.
4) Jerry drives on Wednesday and Friday.
5) Gina drives on Monday and Jerry does not drive on Saturday.

Therefore, it could be true that Jerry drives on Friday.

Hope this helps! Please let us know if you have any further questions.

Quick Note: The instructor on the video states that Jerry ONLY drives on Wednesdays and Saturdays...but here, we're opening the possibility of that not being true. Any clarification on this would be appreciated.
