Basketball – Fun Fair Fun fair Your town holds an annual fun fair. This year there is an intriguing offer at the basketball stand:

“For a $5 entry fee, you are given a basketball and one of two options:
1. One Shot to Score
2. Two out of Three Shots to Score

If you succeed, you are given $20.”

As you have been practicing hard over the school holidays, you decide to pay the $5 entry fee to play this game. According to your mom, you are the next Michael Jordan. And whilst she does exaggerate (sometimes), you estimate that you make 6 out of every 10 shots.

And thus after paying, the fun fair man asks you

“Which option would you like, sir / madam?”

Have a go at the answer!
If you make an estimated 60% of your shots, it is better to take the second bet. The follow up question is. Which success rate ( % of shots made) will make you switch bets. There is an algebraic formula to work this one out. If you figure it out, leave it in the comments section.

Stating the obvious here, but I enjoy riddles & puzzles. Anyone else also struggling with seemingly simple 5th grade math problems?
