Problem of the Week
Problem A
When were you born?

Have you ever thought about whether you were born on an even-numbered or an odd-numbered day of the month? In my family, the four of us were born on odd-numbered days: February \(19\)th, March \(15\)th, September \(7\)th, and December \(3\)rd. Our daughter was born on September \(4\)th, an even-numbered day.

Our best friend just had a baby born in \(2021\).

  1. Is it more likely that the baby was born on an even-numbered day or an odd-numbered day? Justify your answer.

  2. What is the probability that their baby was born on a day that is a multiple of \(5\)?
