  1. How do you calculate Theoretical Probability?
    Chance of Winning Over Total Number of Outcomes.
  2. What is the chance of winning with a spinner like this if you want to land on White?  
    1/6
  3. Out of a deck full of red cards, whats the chance of pulling a green card?
    0%
  4. A spinner has 5 areas. 3 are green and 2 are blue. What is the chance of winning if you want to land on blue?
    40%
  5. If you roll a # cube 600 times, what is the chance of landing on a 3 or a 6?
    200 times out of 600
  6. If you roll a # cube 250 times, what is the chance of landing on a 1,2,3, or 4?
    167 times out of 250 rolls.
  7. Will you always roll a theoretical Probability everytime?
    No, because its an estimated guess, it won't happen every time.
  8. You flip a coin. It lands on heads. Whats the probability?
    1/2, likely as not.
  9. A bowl has 13 red marbels and 5 green marbels. You pick a red marble.
    72%, Likely
  10. A bowl has 13 red marbels and 5 green marbels. You pick a green marble.
    28%, likely as not
  11. A spinner has 100 sections. You land a 101
    0%, impossible
  12. What is a complement?
    The complete opposite of Theoretical. EX: you roll a 3. The complement is not rolling a 3. the complement is rolling a 1,2,4,5,6.
  13. A jar has 10 marbles marked 1-10. You grab 1. The probability of picking a 3 is 1/10. What is the Complement?
    9/10
  14. You have a deck of cards. The probability of picking a king is 1/18. What is the complement of not picking a king?
    18/19.
  15. Why does the probability and complement add up evenly?
    The complement is the opposite of probability, so they will always add up together.
  16. Whats an example of a real world event and its Complement? (No Answer, think of one)
    -
  17. Give 2 examples for a probability of a 100% occurrence and 0% occurrence (No Answer)
    -
  18. You throw a paper cup 20 times. Which outcomes is more likely: side ways, open end up, or open end down?
    Side ways
  19. If you did more experimental trials, what happens to the number?
    It rises
  20. You roll a # cube once. Whats the fraction for landing on any number?
    1/6
  21. Can experimental probabilities be the same as theoretical probabilities?
    Yup
  22. What is the tree diagram?
    The chances in which something can occur.
