The first number in the price of the car is a 1 because it is given.
Based strictly on probability (not factoring in what Drew Carey says about "not selling a 14, 13, 12, or 11 thousand dollar car"), what are the chances that the contestant is correct on the 2nd number in the price being higher than a 5?

1

The contestant gets the third number in the price of the car correct on her second roll. Prior to the roll, what was the probability that she rolled the correct number?

1

The contestant rolls a four on her third roll and guesses the 4th number in the price of the car is LOWER than a 4. What is the probability that she is correct?

1

The contestant rolls a five on her fourth roll and guesses the 5th number in the price of the car is LOWER than a 5. What is the probability that she is correct?

1

Calculate the probability that the contestant wins the car BEFORE the correct numbers are revealed.
HINT: She already knows the 1st and 3rd numbers. She needs higher than a 5 AND lower than a 4 AND lower than a 5.

pulling a blue marble out of a bag, putting it back in, then pulling a green marble out of a bag
