Question

Assume that a procedure yields a geometric distribution where the probability of success is 53%. Use the geometric probability formula to find the probability that the first success occurs after the third trial

A) 0.104

B) 0.531

C) 0.009

D) 0.896

Answer 1

Answer:

A) 0.104

Step-by-step explanation:

$P(X > n)=(1-p)^n\\\\P(X > 3)=(1-0.53)^3\\\\P(X > 3)=(0.47)^3\\\\P(X > 3)\approx0.104$

Answer 2

A) 0.104 i did the math
