I'm not surprised considering the different requirements to take those exams.
To be allowed to take the bar exam in Louisiana you have to be a graduate of a law school accredited by the American Bar Association. That takes 3 years and costs a lot of money.
Before actually taking the bar exam, most graduates then take a third party bar exam prep course for somewhere in the $2k to $4k range, which is an intense course focusing on just passing the bar exam.
To be allowed to take the retail florist license exam in Louisiana, it appears that all you have to do is make an appointment and pay a $114 exam fee. There don't seem to be in education or training requirements, although they do recommend the book "Flowers: Creative Design"  as a reference.
I'd expect then that a lot higher percentage of unprepared people take the florist exam than take the bar exam. If the bar exam was open to anyone who showed up and paid $114 the pass rate would certainly plummet.
