How many events one can define on a sample space of size 6?
Classical Approach
In which approach one has to use the formula P ( E ) = f N, where f is the number of ways that event E may occur and N is the total number of outcomes?
Emperial approach
In which approach one has to construct a relative frequency table and use the relative frequency to estimate the probability of an event?
False
It is impossible to convert odds to probability.
(Not E) - A complement of E
(A and B) - The intersection of A and B
(A or B) - The union of A and B
Match the events with their names:
Not E
A and B
A or B
Venn Diagram
What's the name of the diagram that we use to visualize the events and compound events?
P(A or B) = P(A) + P(B): Special Addition Rule
P(A or B) = P(A) + P(B) - P(A and B): General Addition Rule
P(not E) = 1 - P(E): Complementary Rule
Match the rule with its name:
P(A or B) = P(A) + P(B)
P(A or B) = P(A) + P(B) - P(A and B)
P(not E) = 1 - P(E)
Univariate
A frequency table is an example of a summary of what type of data?
Marginal/Joint
The probabilities of events obtained from the rightmost column and the bottom row are called _________ probabilities. The probabilities of events obtained from the cell at the intersection of i-th row and j-th column are called _________ probabilities.
Prior/Posterior
In the definition of conditional probability, P(A) is called _________ probability, and P(A|B) is called _________ probability.
P(A and B) = P(A)P(B): Special Multiplication Rule
P(A and B) = P(A)P(B|A): General Multiplication Rule
Match the rule with its name:
P(A and B) = P(A)P(B)
P(A and B) = P(A)P(B|A)
