It si cool so basicly u take 5 divide bye 13 times 5
Let X be a discrete random variable with geometric distribution.
Let x be the number of tests and p the probability of success in each trial, then the probability distribution is:
P (X = x) = p * (1-p) ^ (x-1). With x = (1, 2, 3 ... n).
This function measures the probability P of obtaining the first success at the x attempt.
We need to know the probability of obtaining the first success at the third trial.
Where a success is defined as a customer buying online.
The probability of success in each trial is p = 0.3.
So:
P (X = 3) = 0.3 * (1-0.3) ^ (3-1)
P (X = 3) = 0.147
The probability of obtaining the first success at the third trial is 14.7%

Step-by-step explanation:
Male betta fish will place the eggs into a bubble nest, which he will create. The baby betta fish will hatch in about three days. As they hatch, male betta fish will watch and remain under the bubble nest, catching any eggs that fall out. Once hatched, the babies are called "fry" and are very tiny.
