Id	Name	Note
1	Each face of a fair 14-sided die is labeled with a number from 1 through 14, with a different number appearing on each face. If the die is rolled one time, what is the probability of rolling a 2?	A) \$12/14\$ B) \$2/14\$ C) \$1/14\$ D) \$13/14\$
2	The table shows the number of different colors of marbles in a bag. If a marble is chosen at random from the bag, what is the probability that the marble will be blue? $2$	A) \$10/40\$ B) \$18/40\$ C) \$30/40\$ D) \$22/40\$
3	The table summarizes the distribution of color and shape for 100 tiles of equal area. $3$ If one of these tiles is selected at random, what is the probability of selecting a red tile? (Express your answer as a decimal or fraction, not as a percent.)	A) \$9/10\$ B) \$7/10\$ C) \$5/7\$ D) \$3/10\$
4	The number of penguins in a zoo exhibit, sorted by gender and type of penguin, is shown in the table above. Which type of penguin has a female population that is the closest to being \$1/3\$ of the total female penguin population in the exhibit? $4$	A) Macaroni B) Chinstrap C) Emperor D) Gentoo
5	Suppose you have a standard deck of 52 playing cards, and you randomly draw one card from the deck. What is the probability of drawing a face card (jack, queen, or king)?	A) \$3/13\$ B) \$3/16\$ C) \$5/13\$ D) \$7/16\$
6	Suppose you have a bag containing 5 red balls, 3 green balls, and 4 blue balls. If one ball is randomly selected from the bag, what is the probability that it is either red or green?	A) \$11/9\$ B) \$2/3\$ C) \$4/9\$ D) \$8/3\$
7	In a bag, there are 8 red, 5 white, 27 blue, and 30 yellow cubes. If one of these cubes is selected at random, what is the probability of selecting a cube that is neither blue nor yellow?	A) \$17/70\$ B) \$16/60\$ C) \$13/70\$ D) \$23/60\$
8	In a classroom, there are a total of 60 students. Each student is either studying mathematics, physics, or chemistry. If the probability of selecting a student studying mathematics is 0.4 and the probability of selecting a student studying physics is 0.3, what is the probability of selecting a student studying chemistry?	A) 29 B) 13 C) 22 D) 18
9	In a class, students are randomly assigned to one of three projects: Project A, Project B, or Project C. If 40% of the students are assigned to Project A and 25% are assigned to Project B, what percentage of students are assigned to Project C?	A) 35% B) 42% C) 31% D) 39%
10	Let’s make it more challenging by considering a scenario where the daily registration rate changes over time.Let’s say the daily registration rate follows a pattern where it starts at 1,200 on the first day and increases by 100 each subsequent day. To find out how many accounts are registered in the first 5 days, we need to sum up the registrations for each day. This involves finding the sum of an arithmetic sequence.	A) 7,200 B) 7,000 C) 7,100 D) 6,900
