Question 1036345: The game of Fizzbin is played with a deck of 30 cards. There are three colors (red, black, blue), with 10 cards in each color (cards are numbered from 1 to 10). Cards are drawn without a replacement.
1)If a card is drawn at random, what is the probability that the card is a 10?
2)If the first card is a 10, what is the probability that the second card will also be a 10?

You can put this solution on YOUR website! The game of Fizzbin is played with a deck of 30 cards. There are three colors (red, black, blue), with 10 cards in each color (cards are numbered from 1 to 10). Cards are drawn without a replacement.
1)If a card is drawn at random, what is the probability that the card is a 10?
P(card is a 10) = 3/30 = 1/10
-------------------------------------
2)If the first card is a 10, what is the probability that the second card will also be a 10?
P(10 after 10) = (3/30)(2/29 = 0.00690
