Answer: (4/5)^7 x 1/5

Step-by-step explanation: This is a geometric probability distribution. The probability of a success is 20% = 1/5 and the probability of a failure is therefore 4/5.

We want to know the probability that Ben is successful on the eight attempt. This means he has failed the first 7 times but succeeds on the 8th try.

So probability is (4/5)^7 x 1/5

Using sampling concepts, it is found that this is an example of independent samples.

  • For dependent samples, there is a paired measurement for one set of items.
  • For independent samples, separate measurements are made on two different sets, that is, the value on one sample reveal no information about the values on the other sample.

In this problem, there are two samples, the sample composed of male workers and the one composed of female workers, and separate measurements are taken, hence, it is an independent sample.

Verdich [7]

Answer:

Plane T

Step-by-step explanation:

The given points A, D, and E are shown as being on the plane T as follows

Point a lays on the boundary of the boundary between plane S and plane T

Points D and E are points on a line DE that is on the plane T

Therefore, given that the line DE and the point A all lay on the same plane T, the plane that contains points A, D, and E, is plane T.
