In a standard deck of cards, there are 4 types of cards: spades, hearts, clovers, and diamonds.
On your first draw, you have a 25% chance to get a spade, because 1/4 = 25%.
If you got a spade on your first draw, then the chance of you getting a heart on your second draw is 13/51.
This is because you already took a card from the deck, and there are 13 cards that are hearts.
When we multiply 1/4 and 13/51, we get 13/204 as an exact answer.
19 integers, with one in the middle being 99.
Before 99, there is 98, 97, 96 . . . 90.
After 99, there is 100, 101, 102 . . . 108.
This is because the average of 98 and 100 is 99, and so is every other pair.
I dont even know what I'm sayin, anyways, 108 is the largest integer this problem is too easy to explain.
