“I am a time traveller!” said the time traveller. “Bullshit!” said I. “I will prove it to you. Get a fair dice. Color the side 1,2 and 3 as red. Color the sides 4 and 5 as green. And finally colour the side 6 as blue.” I did as the traveller asked.
“Now I will write down the color which you will roll” said the traveller and wrote down something on a piece of card which was placed face down so I could not see what was written.
“Roll the die!” the time traveller demanded. I did. “now watch this!” the traveller said and turn over the card.
The card showed a word correctly described the color of the side of the dice which I rolled.
Question: Assuming the time traveller is a Fraud, what is the probability of writing down the correct result on the card before I rolled the dice?
