Proficiency Scale Vocabulary

5. Probability The probability of an event occurring given that another event has already occurred; Denoted as P9A/B), the probability of event A given event B.
6. Number A number that can be written as a fraction, including integers, fractions, and terminating or repeating decimals.
8. The set of outcomes that are in both events.
10. Exponent An exponent that is a fraction, representing roots of a number.
11. Events Two events are independent if the occurrence of one event does not influence the occurrence of the other.
14. A number that tells how many times to multiply the base by itself.
15. Events Two events are dependent if the occurrence of one event affects the probability of the other event.
17. The measure of the likelihood that a given event will occur, typically expressed as a ratio of favorable outcomes to total possible outcomes.
19. Formula A mathematical formula used to calculate the likelihood of an event occurring , typically expressed as P(A)=number of favorable outcomes/total number of outcomes.

1. A possible result of a probability experiment.
2. To calculate the value of a mathematical expression.
3. To examine two or more numbers to determine their similarities and differences.
4. The four basic mathematical processes: Addition, Subtraction, Multiplication, and Division.
7. Number A number that cannot be written as a fraction because its decimal form goes on forever without repeating.
9. To change a number from one form to another, such as a fraction to a decimal.
12. of Numbers The mathematical rules that describe how numbers behave, such as distributive, commutative, and associative properties.
13. The set of outcomes of a probability experiment that may or may not occur.
16. Space the set of all possible outcomes in a probability experiment.
18. Exclusive two events are mutually exclusive if they cannot both occur at the same time.
