If a procedure meets all of the conditions of a binomial distribution except the number of trials is not​ fixed, then the geomet
morpeh [17]

Answer:

The probability is 0.0428

Step-by-step explanation:

First, let's remember that the binomial distribution is given by the formula:

P(X=k) =\left[\begin{array}{ccc}n\\k\end{array}\right] p^{k}(1-p)^{n-k} where k is the number of successes in n trials and p is the probability of success.

However, the problem tells us that when there isn't a number of trials fixed, we can use the geometric distribution and the formula for getting the first success on the xth trial becomes:

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

The problem asks us to find the probability of the first success on the 4th trial (given that the first subject to be a universal blood donor will be the fourth person selected)

Using this formula with the parameters given, we have:

p = 0.05

x = 4

Substituting these parameters in the formula and solving it, we get:

P(X=4) = 0.05(1-0.05)^{4-1}\\P(X=4) = 0.05 (0.95)^{3}\\P(X=4) = 0.05(.8573)\\P(X=4) = 0.0428

Therefore, the probability that the first subject to be a universal blood donor is the fourth person selected is 0.0428 or 4.28%

The population of a community, p(x), is modeled by this exponential function, where x represents the number of years since the p
NeX [460]

An exponential model is used to represent growth of a population

The population after 3 years is 2585

The function is given as:

\mathbf{P(x) = 2400(1.025)^x}

<em>3 years after</em>, means that x = 3

So, we have:

\mathbf{P(3) = 2400(1.025)^3}

Evaluate exponents

\mathbf{P(3) = 2400 \times 1.076890625}

\mathbf{P(3) = 2584.5375}

Approximate

\mathbf{P(3) = 2585}

Hence, the population after 3 years is 2585
