How do you solve problems like this?
Probability Mass Function of Geometric (p) distribution is f(x) = (1-p)^x-1 p, x = 1,2,...
If the number of orders this month is a Geom(0,7) random variable, find the probability that we have at most 3 orders.
The following information is provided:-
The population proportion of success is p=0.7, also, 1 - p = 1 - 0.7 = 0.3
We need to compute
Therefore, we get that
This implies that
which means that the probability we are looking for is

A discrete random variable X follows the geometric distribution with parameter p, written X ∼ Geom(p), if its distribution function is A discrete random variable X follows the geometric distribution with parameter p, written X Geom(p), if its distribution function is 1x(z) = p(1-P)"-1, ze(1, 2, 3, ). The Geometric distribution is used to model the number of flips needed before a coin with probability p of showing Heads actually shows Heads. a) Show that fx(x) is indeed a probability...

4. Given that X has a geometric distribution, that is the probability mass function is P(X) = p(1-p)x-1 , prove that the mean of the geometric distribution is 1. (Hint: You will have to use the sum of an infinite geometric series)
We have seen that the geometric distribution Geo(p) is used to model a random variable, X that records the trial number at which the first success isachieved after consecutive failures in each of the preceding trials ("success" and failure being used in a very loose sense here). Here, p is the success probability in each trial. We described the geometric distribution using the probability mass function: f(X)(1- p)*-1p, which computes the probability of achieving success in the xth trial after...
Find the probability generating function of a discrete random variable with probability mass function given by pX(k) = qk−1p, k = 1,2,..., where p and q are probabilities such that p + q = 1. We shall see later that this is called the geometric distribution function.
