He’s hoping to pass his newfound knowledge onto you. You will receive The Best in the Class achievement upon answering all five questions correctly, giving you a golden badge under the Record tab in the Main Menu.

A Mersenne prime is a prime number that is one less than the power of two. 2,147,483,647 is the largest known prime that can fit inside a 32-bit integer field. The answer is derived from these calculations: 10! / (3! * 2!)10! = 3,628,800, 3! = 6, 2! = 2. 3,628,800 / (6 * 2) = 3,628,800 / 12 = 302,400.

A happy palindromic number is a number that reads the same forwards and backwards that always reaches one when replaced by the sum of its digits. With 29 happy palindromic numbers here, the sum you need to work out the size of the powerset is 2^29.2^29, which gives you the answer to the fourth question in Chester’s quiz.

Question five: Given that the answer is a natural number with nine digits, the probability of guessing this question correctly at random is one in

Answer: 900000000

The only question that feels like a trick, The answer is within how the question is written. The “9 digits” tells us that the answer must be nine digits long, so you simply need to add eight zeros after nine.
