''We talked about birthdays in the context of one of the textbook exercises for ''OpenIntro'' Chapter 3. Here's an opportunity to apply your knowledge and extend that exercise. Note that you can absolutely use R to help calculate the solutions to both parts of this problem. That said, it's a super famous problem and answers/examples are all over the internet, so if you want to challenge yourself, don't look at them while you're working on it! The only hint I'll give you is that you may find [https://en.wikipedia.org/wiki/Binomial_coefficient binomial coefficients] useful and the <code>choose()</code>) function can calculate them for you in R.'' | ''We talked about birthdays in the context of one of the textbook exercises for ''OpenIntro'' Chapter 3.
