A set of homemade toy playing cards * * * has 52 cards in four colors: hearts, diamonds, spades and clubs, with one card for each color 1- 13.

The first question

Considering the most unfavorable situation, first, all the 13 cards of two colors are drawn out.

A * * * 13× 2 = 26

Feel free to touch another card to make sure that the two cards have the same number of points and color.

Therefore, at least 26+ 1 = 27 cards can be found at a time to ensure that two of them have the same points and colors.

the second question

Points are 1 ~ 13.

Consider the most unfavorable situation

First of all, I found 1, 3, 5, 7, 9, 1 1, 13.

A * * * 4× 7 = 28 sheets.

Feel free to touch the other one, and make sure there are three adjacent points.

28+ 1=29

Therefore, to draw at least 29 cards, there must be three adjacent points.
