Situation D: Suppose that, in a one-minute period during an electrical storm, the number of lightning strikes on a radar antenna

Crank

Answer:

21.77% probability that the antenna will be struck exactly once during this time period.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

In this question:

$\mu = 2.40$

Find the probability that the antenna will be struck exactly once during this time period.

This is P(X = 1).

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 1) = \frac{e^{-2.40}*2.40^{1}}{(1)!} = 0.2177$

21.77% probability that the antenna will be struck exactly once during this time period.

Suppose a researcher is surveying four subjects: subject A, subject B, subject C, and subject D. Subject B wants to impress the

Lina20 [59]

Answer:

Subject B.

Step-by-step explanation:

It is given that,

There are total four subjects, namely A, B, C and D.

Out of these four subjects, we have, Subject B wants to impress the researcher above everyone while the other subjects do not care.

Since, Subject B wants to impress the researcher, they would want to use any means as possible so that the researcher gets amazed by them.

For this, it is highly possible that they will start answering questions in a way that makes them impressive, which would lead them to not answer questions honestly.

While the other subjects do not care whether the researcher is impressed, this will make them give the answer honestly.

Hence, Subject B is least likely to answer the questions honestly.
