UNIT 8, LESSON 9 PROBABILITY UNIT TEST (for connexus)
1. 17/30 - A survey taken by 150 people revealed that 65 like apple juice while 85 dislike it. One person is randomly chosen from this group. What is the chance that the chosen person dislikes apple juice? Write your answer as a ratio in simplest form
2. S AND I - A letter is to be randomly picked from the word MISSISSIPPI. Which set of letters have equal chances to be selected?
3. 1/3 - A six-sided number cube is rolled 30 times and lands on 3 ten times and on 5 eight times. Calculate the experimental probability of landing on a 3. Write your answer in the simplest form of a fraction
4. 11/40 - The experiment involved tossing three coins simultaneously. The experiment was carried out 100 times, and it was noted that three heads occurred 40 times. What is the difference between the experimental probability of getting three heads and its theoretical probability? Write the answer in the simplest form of fraction
5. 1/4 - An experiment involves picking a card from the number cards 2, 4, 6, 10 2 , 4 , 6 , 10 . In equation form. What is the probability model for this experiment
6. 75 - Suppose the probability of selecting a supermarket shopper who prefers plastic bags instead of paper bags is 50%. Out of 150 shoppers, how many can you expect will prefer plastic bags?
7. 120 - A spinner has 8 equally sized sections labelled as A, B, C, D, E, F, G, H A , B , C , D , E , F , G , H . In 160 spins, how many times can you expect to spin on a consonant?
8. 0.4 - A single coin is tossed 300 times. Heads were observed 180 times. What is the long-run relative frequency of tails? Express the answer in decimal form
9. F x 1/3, Where r 5, 10, 15 - An experiment involves picking a card from a selection of cards numbered 5, 10, and 15. In equation form, what is the probability model for this experiment? List the values of x x in ascending order
10. 0.10 - If the table below represents a probability model based on observed frequencies, what is the value of x x ?
11. 100 - Bowls A and B contain a number of white and red balls. Clark repeatedly selected a ball from both bowls and recorded the results in a table. If there are 500 balls in Bowl B, what is the estimated difference in the expected number of white and red balls in Bowl B?
12. 1/4 - What is the probability of rolling an odd number on the first roll of a six-sided cube and rolling an even number on the second roll?
13. 5/51 - A big flower vase has 5 begonias, 6 carnations, and 7 tulips. Two flowers are randomly selected without replacement. What is the probability of selecting two carnations? Express the answer in the simplest form of fraction
14. 5.88% - A standard deck of 52 cards contains four suits: hearts, diamonds, clubs, and spades. Each suit has 13 cards: ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, and king. Two cards are randomly drawn without replacement. Calculate the probability of drawing two diamond cards. Express your answer in percent form rounding to the nearest hundredth
