Imagine a game of dice: if the biggest number rolled is one, two, three, or four, player 1 wins. If the biggest number rolled is five or six, player 2 wins. Who has the best probability of winning the game? Leonardo Barichello explains how probability holds the answer to this seemingly counterintuitive puzzle. Lesson by Leonardo Barichello

Orrr player one could eat the banana and then eat the cat, cats cant eat bananas anyways. Also when youre starving any thing can be food so eat the cat. also if you dont want to eat the cat just fish for some food there is water all around them, Meaning there will probably be life to eat. Then you and the cat get to eat. make a rode from tree to fish with. Orrr just let player one use their hands to pick up a small fish then eat(or you can make a fire with the tree if you dont want to eat raw fish but in would use that tree for a raft.

From the rules agreed to, you didnt mention that you are going to add the 2 together. Only through the examples can we see that youve changed/expanded the rules.
Interesting experiment, but I think I could make a case that the rules are what we agreed to, anything after that is only your interpretation of those rules, which you could change in your favor depending on the outcome. No, Im not a lawyer.

Took this to VBA for a test of 10. 000. 000. Giving the following wins
Ta = 5555139
Tb = 4444861
So the Rnd of VBA seems to work just as expected.
Sub banana)
Dim Ta, Tb, count, A, B As Long
For count = 1 To 100
Ta = Int(6 Rnd) + 1
Tb = Int(6 Rnd) + 1
If Ta >= 5 Or Tb >= 5 Then A = A + 1 Else B = B + 1
Next count
Debug. Print A, B
End Sub

I didn't really understand the joint probability explanation. If you calculate the probability for the cat, it should win if the highest is 5 or six, so that would be 1 in 3 for each dye. The joint probability should then be 1/9, while the probability of the girl winning is 4/9. the player 1 has a higher chance of winning an the probabilities don't add up to 1. Can anyone explain?

Plot twist.
The cat wins and eats the banana.
But, alas it is allergic and dies.
The girl knew this all along and make stew out of the cat

How is this a thought experiment?
A thought experiment in subtraction: Imagine 4 bananas, and you decide to eat three. You now have only one banana.
