Probability Flashcards
1
Q
What is an experiment
A
A repeatable process that gives rise to a number of outcomes
2
Q
What is an event
A
A collection of one/more outcomes
3
Q
What is a sample space
A
The set of all possible outcomes
4
Q
When estimating using interpolation
A
We are assuming that
the class is continuous when we interpolate, and that the probability of being exactly equal to any
individual value is negligible.
5
Q
Mutually exclusive events
A
Have no outcomes in common, P(AUB) = P(A)+P(B)
P(ANB) = 0 (Intersection is the empty set)
6
Q
Independent events
A
When one event doesn’t affect the other
P(A)xP(B) = P(ANB)
7
Q
Conditional for independent events
A
P(A|B)=P(A|B’)
8
Q
Addition formula for events
A
P(AUB) = P(A) + P(B) - P(ANB)
9
Q
Multiplication formula
A
P(B|A) = P(BNA)/P(A)
