Question by Lookingforadvice: Help with a geometry bonus question?? PLEASE?
The casino manager wished to check the bias on the roulette wheel, so he asked six of his croupiers to report back to him at the end of the week with the number on the wheel which had been most successful.
The wheel consisted of 36 numbers 1 to 36 with no zero.
These were the 6 answers:
A said, “It was even.”
B said, “It was odd.”
C said, “It was prime.”
D said, “It was square.”
E said, “It had at least one 2 in it.”
F said, “It was a single digit.”
(The number 1 is not considered to be a prime number.)
But two had lied. Which number was most successful?

Best answer:

Answer by Joel J
2. Its even, its prime, it has at least one “2″ in it, and it is a single digit. B and D are lying.
