1 Name: Class: Date: Question #1 Jordan has a bag of marbles and a spinner. The bag of marbles has 10 marbles in it, 6 of which are red. The spinner is divided into 4 equal sections: blue, green, red, and yellow. What is the probability Jordan will pick a red marble out of the bag and land on the red section when spinning the spinner? 60% 40% C 2% D 1% Page 1 of 13
2 Question #2 There are 12 boys and 16 girls in Marco's class (including Marco).What is the probability that a student chosen at random from Marco's class will be a boy? C 3 7 D 2 Question #3 Olivia has a box of 20 colored tiles. There are four types of colors including black, green, white, and yellow. There are 8 black tiles, 4 green tiles, 3 white tiles, and yellow tiles. Olivia will pick a tile from the box without looking, record its color, and put it back in the box. If Olivia does this 400 times, about how many times can she expect to pick a green tile? 4 20 C 40 D 80 Page 2 of 13
3 Question #4 fair coin is tossed 4 times. What is the probability that tosses will result in 3 heads and 1 tails in any order? C 1 4 D 3 4 Question # Tyree and rad are each given a bag of marbles. Tyree's bag of marbles has a total of 8 marbles in it, 2 of which are red. rad's bag has a total of 10 marbles in it, 4 of which are red. If both Tyree and rad reach into their bags and pull out a marble, which is more likely to pull out a red marble and why? C D rad. He has a 2% better chance to pull out a red marble. rad. He has a 1% better chance to pull out a red marble. Tyree. He has a 2% better chance to pull out a red marble. Tyree. He has a 1% better chance to pull out a red marble. Page 3 of 13
4 Question #6 Isaiah is ordering a sub sandwich for lunch. He can have turkey, ham, chicken, roast beef, or tuna. His bun choices are wheat, honey oat, and white. How many different sub combinations can Isaiah order? 1 12 C 4 D 7 Question #7 box contains red marbles, 8 white marbles, and 4 green marbles. One marble is taken out of the box at random.

5 Question #8 2 bag contains pink, yellow, and green marbles. The probability of randomly selecting a pink marble is. 1 The probability of randomly selecting a yellow marble is. 3 Which statement is true? C D Pink is the least likely colored marble to be randomly selected. Yellow is the least likely colored marble to be randomly selected. Green is the least likely colored marble to be randomly selected. There is not enough information to determine which is least likely to be randomly selected. Question #9 There are 4 colors of Starburst flavors: yellow, pink, red, and orange. If the probability of getting an orange is, yellow is, and the probability of getting red is, what is the probability of getting pink? C 2 D 4 10 Page of 13
