Geometric Distribution Flashcards
1
Q
what is a geometric ?
X~ Geo(p)
A
how many trials occur, each with a probability p until the first sucess is seen
2

A
4
Q
what is the mean and variance of a geometric distibution?
A
mean = reciprocal of propability

6
Q
what conditions must apply for a geometric distribution to be used?
A
- two outcomes (sucess/ failure on each trial)
- independant trials
- probability of sucess is constant
- finding number of trials for dirst sucess to occur
