Entry to @jaycee7viral's mind game contest
Level 1
Answer:
Put one red marble in one bowl, and put the remainder of the marbles in the other bowl.
After the blindfolds are applied and the bowls are shuffled, you will pick up the bowls and choose the lighter one (or feel inside and choose the bowl with just one marble). Select the marble from that bowl and you will live!
Reasoning:
By placing one red marble in one bowl, the probability of selecting the correct marble for that bowl is 100%. The instruction states, “You can choose one bowl and remove one marble”, but it does not define how you may choose your bowl. It does not specify if you may lift both bowls or feel around in the bowl before making your selection. In both cases, you will have a 100% probability to selecting the red marble based on the weight of the bowl or feeling a single marble versus a pile of marbles.
Level 2
Answer:
Jeff is the murderer.
Reasoning:
| Name | Victim? | Murderer? | Reasoning |
|---|---|---|---|
| Ben | N | N | Ben met Jack for the first time six months ago, therefore he is not his brother and cannot be the murderer |
| Dan | ? | N | Dan ran in the NY City marathon and since the murderer has an amputated leg, so Dan cannot be the murderer |
| Jack | N | N | Jack's brother is the murderer so Jack cannot be the murderer |
| Jeff | N | ? | Jeff wants to install Ben's PC next week which means he is still alive with future plans, so he cannot be the victim which concludes that he is the murderer |
| Mike | ? | ? | Mike and Dan are the only possible victims. If Dan is the victim, there is no way to tell if Mike or Jeff is the murderer. Sherwin grey was able to identify the murderer, so therefore Mike has to be the victim which points to Jeff as the murderer |
Level 3
Answer:
First, carry the chicken across the river.
Second, carry bag of corn across the river and bring back the chicken.
Third, drop off the chicken and carry the fox across the river.
Lastly, come back and carry the chicken across the river.
Reasoning:
There is no combination of carrying one thing at a time across the river that would protect the lives of all individual after you leave. The key is to separate the chicken from the group because it can eat and be eaten. You must carry it back and forth on some trips to maintain the separation.
