1. **Stating the problem:**
We have a deck of 52 cards, and we want to find two things:
- How many cards can be chosen from the deck?
- How many cards must be chosen to guarantee at least three gilts (assuming "gilts" means a specific type of card, e.g., a suit or rank).
2. **Understanding the deck:**
A standard deck has 52 cards divided into 4 suits, each with 13 cards. If "gilts" refers to one suit, there are 13 gilts.
3. **How many cards can be chosen?**
You can choose any number of cards from 0 up to 52. So the number of cards that can be chosen ranges from 0 to 52.
4. **How many cards must be chosen to have at least three gilts?**
We use the pigeonhole principle here.
- There are 13 gilts.
- To guarantee at least 3 gilts, consider the worst case: you pick as many cards as possible without getting 3 gilts.
5. **Worst case scenario:**
- You can pick at most 2 gilts without reaching 3.
- You can pick all non-gilt cards: 52 - 13 = 39 cards.
6. **Total cards picked without 3 gilts:**
$$ 2 \text{ (gilts)} + 39 \text{ (non-gilts)} = 41 $$
7. **Therefore, to guarantee at least 3 gilts, you must pick:**
$$ 41 + 1 = 42 $$
**Final answers:**
- Number of cards that can be chosen: any number from 0 to 52.
- Number of cards to guarantee at least 3 gilts: 42.
