Solution :
Given that, the probability of success on any one trial p = 0.15 ,
x = 8
=> In a geometric distribution, the probability of getting the first success on the xth trial is given by
P(X = x) = p*(1 - p)^(x - 1)
=> P(8) = P(X = 8)
= 0.15*(1 - 0.15)^(8 - 1)
= 0.0481
=> The Probability that the first defect is found in the eighth component tested is 0.0481

If a procedure meets all of the conditions of a binomial distribution except the number of trials is not fixed, then the geometric distribution can be used. The probability of getting the first success on the xth trial is given by P(x)=p(1-p)x-1, where p is the probability of success on any one trial. Subjects are randomly selected for a health survey. The probability that someone is a universal donor (with group O and type Rh negative blood) is 0.07. Find...
18). -1 If a procedure meets all of the conditions of a binomial distribution except the number of trials is not fixed, then the geometric distribution can be used. The probability of getting the first success on the xth trial is given by P(x) = p(1 - p)*', where p is the probability of success on any one trial. Subjects are randomly selected for a health survey. The probability that someone is a universal donor (with group O and type...

Use either the binomial...
The geometric distribution is a probability distribution of the number X of Bernoulli trials needed to get one success. For example, how many attempts does a basketball player need to get a goal. Given the probability of success in a single trial is p, the probability that the xth trial is the first success is: Pr(x = x|p) = (1 - p*-'p for x=1,2,3,.... Suppose, you observe n basketball players trying to score and record the number of attempts required...
