Whether you celebrate Chinese New Year, Spring Festival or Seollal, we hope you have a safe and fun holiday. 🐓🏮 During the Lunar New Year, it’s common to hear some repeated phrases said to friends, family and even strangers.

Unfamiliar with the Lunar New Year? Solve set 58 teaches you not just arithmetic, volume of a cylinder, ideal gas law and more but also all about the culture of the new year following the Lunar Calendar.
Take a look at Problem 2: A Red-Letter Day
Keeping with the tradition of giving red envelopes during the Chinese New Year, you and your cousins always exchange envelopes in order to pass along good luck. In your group of people, the tradition is for every person to give a red envelope to every person who is younger than them, with an amount of money proportional to the age difference. The ages in this group are 1, 30, 32, 35, 36, 37, and 39. One of the people ends up giving and receiving the exact same amount of money. What is the age of that person?
This year is the year of the Rooster! Did you know roosters are larger, usually more brightly colored than chickens? Try out Problem 4: Walkin’ Rooster Oracle
A rooster starts at the position 2017 on a number line. Every minute, the rooster flips a fair two-sided coin, and moves one step to the right if the coin lands heads, and one step to the left if the coin lands tails. The Wise Rooster Oracle predicts that the rooster will *eventually* reach position 2500 *before* reaching position 0. Assuming that this information from the future is accurate, what is the probability that the *first coin flip* will be heads (so after the first minute, the rooster will move to 2018 rather than 2016)? Write your answer as a fraction p/q in simplest terms.
