Vocabulary
The number you get when you add the first two branches of a tree diagram.
What is total sampled?
The probability of event A or event B?
What is P (A u B) ?
A two circle diagram to represent similarities and differences.
What is a Venn diagram?
The formula P(a u b)= P(a) + P(b) - P(a n b) is used to find the probability of this.
What is the probability of A OR B?
The probability of rolling a dice and it landing on a 6.
What is (1/6)?
The probability figured by performing trials and recording results.
What is experimental probability?
The probability of event A and event B.
What is P(A n B)?
Representing how 2 or more groups relate to 2 or more other groups based on how many participants are within each intersection of groups
What is 2-way frequency table.
One way to find P(a n b) if events are independent.
What is P(a)P(b) ?
The probability you roll a 3 on your second roll given that you rolled a 3 on your first roll?
What is (1/36)?
The probability that comes from calculations and what is expected.
What is theoretical probability?
The probability of event X given event Y.
What is P (X|Y)?
A diagram where each choice leads to more branches.
What is a tree diagram?
The probability that P(b|a) should be equal to if a and b are independent.
What is P(b)?
This is independent or dependent:
You draw a red marble out of a bag, replace it, and then draw a yellow marble.
What is independent?
The type of probability that is a category over the total sampled.
What is marginal probability?
The probability that a student who does their homework (H) has an A (A).
What is P(A|H)?
The best diagram for showing conditional probability.
What is a tree diagram?
The probability that is equivalent to P(a n b) / P(b) given a and b and independent.
What is P(a)?
If we roll two dice, the probability that our sum is greater than nine.
What is (6/36) = (1/6)?
The type of probability that is the intersection of two events over the total sampled.
What is joint probability?
The probability symbol that will produce a larger probability (greater chance) between U (or) or n (and).
What is U?
The best diagram to show easily how many students are taking BOTH band and choir.
What is a Venn Diagram?
These events are independent or not:
P (A) = 1/2
P(B) = 1/3
P (A n B) = 1/12
What is no, not independent?
The probability of P(B) = 70/150. The probability of A would need to be this in order for the events to be independent.
What is 33?
