Assume that a procedure yields a geometric distribution where the probability of success is 19%. Use the geometric probability f

Rudiy27

The probability that the first success occurs on the third trial is 0.125.

Answer: Option C

Step-by-step explanation:

The probability of success is given by the geometric distribution formula:

$P(X=x)=p \times q^{x-1}$

Where,

p = probability of success for single trial.

q = probability of failure for a single trial (1-p)

x = the number of failures before a success.

P(X = x) = Probability of x successes in n trials.

Given:

p = 19% = 0.19

q = 1 – p = 1 – 0.19 = 0.81

x = 3

We want to find the probability that the first success occurs on the third trial so,

$P(X=3)=0.19 \times 0.81^{(3-1)}$

$P(X=3)=0.19 \times 0.81^{2}$

$P(X=3)=0.19 \times 0.6561=0.125$

   f(x) = x² + 2
   y = x² + 2
         x = y² + 2
    x - 2 = y²
√(x - 2) = y
√(x - 2) = f⁻¹(x)
