Geometric Distribution

a discrete probability distribution of a random variable x that satisfies the following conditions

2
New cards

factors of Geometric distribution

  1. a trial is repeated until a success occurs.

  2. The repeated trials are independent of each other

  3. The probability of success p is the same for each trial

  4. The random variable x or r represents the number of the trial in which the first success occurs

3
New cards

the probability that the first success will occur on trial number x is

P(x)=p(1-p)^n-1 , where n =1,2,3
