Answer:

You can use proportions by settling the ratio from the sample equal to the ratio from the population.

Explanation:

For Example is 3 out of 50 phones in a sample are defective, then an estimated 60 out of 1000 phones in a population are defective. this can be found by solving the proportion 3/50=x/1000 where x is the estimated number of defective phones in the population.

Proportions which would be equal to the ratio from the sample equal to the ratio from the population.

Step-by-step explanation:

I find that Proportions are the easiest way.

Answer:

We can write out 3! (three factorial) as 3x2x1, and we can write out 5! as 5x4x3x2x1. This means that, since 3x2x1 is on the top and the bottom of the fraction, it cancels out. This leaves us with 1 on top, and 4x5=20 on the bottom.

Consider an unstructured overlay network in which each node randomly chooses c neighbors. If P and Q are both neighbors of R, wh

Fed [463]

The probability value become is 2c/(N-1).

According to the statement

we have given that If P and Q are both neighbors of R, and by considering unstructured network in which each node randomly chooses c neighbors.

we have to find that the probability of neighbors that they are also neighbors of each other.

So, For this purpose to find the probability is

Consider a network of N nodes unstructured and let

If each node chooses c neighbors at random,

then the probability that P will become by choose Q, or Q chooses P is roughly 2c/(N-1).

And the probability outcomes value become is 2c/(N-1).

So, The probability value become is 2c/(N-1).
