Silly probability problem, need confirmation.

A box contains 4 red cards, 6 g blue cards, and 10 green cards.
What is the smallest number of cards we must remove from the box to get 2 cards of THE SAME COLOR?
Is it 4?

2. Max is reading a book. He has read 1/4 of the book. If he stopped at page 67, how many pages are in there fully?
3. 4 lines can intersect at a maximum of... x points. Find x.
4. CD is 6 inches from AB and AB is parallel to CD. Point K is 4 inches from AB and not between the two lines. How many points on CD are exactly 10 inches from K?
5. If 5 different distinct integers sum to 55, what is the largest value any of these numbers can have?

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

If 100 consecutive multiples of 3 are written in order, what is the diff between the largest and smallest number? Is it 297?
