Version 1 09/13

Read the following scenario and complete each of the four problem sets below:

Suppose we have a special deck of ten cards that have the following designs:

 The number 0 and a red square

 The number 1 and a blue square

 The number 2 and a green square

 The number 3 and a red circle

 The number 4 and a blue circle

 The number 5 and a green circle

 The number 6 and a yellow circle

 The number 7 and a blue triangle

 The number 8 and a green triangle

 The number 9 and a black star 1. Using the 10 card deck, how many sets of 3 can be made if the order of the cards does NOT matter? How many sets of 3 cards can be made if order does matter? Explain the difference between these two questions. <Compose answer here> 2. Suppose 2 cards are selected without replacement:

a. What is the probability of drawing a card with a different color if the first card is the black star? b. What is the probability of drawing a card with a different shape if the first card is the green square?

c. What is the probability of drawing 2 blue cards? d. What is the probability of drawing 2 circle cards? e. What is the probability of drawing 2 blue cards OR 2 circle cards? f. What is the probability of drawing 2 blue cards AND 2 circle cards? a. b. c. d. e. f.
