Viefleur [7K]

Answer:

$c = \frac{1}{12}$

The mean of the distribution is 0.25.

The variance of the distribution is of 0.6875.

Step-by-step explanation:

Probability density function:

For it to be a probability function, the sum of the probabilities must be 1. The probabilities are 3c, 3c and 6c, so:

$3c + 3c + 6c = 1$

$12c = 1$

$c = \frac{1}{12}$

So the probability distribution is:

$P(X = -1) = 3c = 3\frac{1}{12} = \frac{1}{4} = 0.25$

$P(X = 0) = 3c = 3\frac{1}{12} = \frac{1}{4} = 0.25$

$P(X = 1) = 6c = 6\frac{1}{12} = \frac{1}{2} = 0.5$

Mean:

Sum of each outcome multiplied by its probability. So

$E(X) = -1(0.25) + 0(0.25) + 1(0.5) = -0.25 + 0.5 = 0.25$

The mean of the distribution is 0.25.

Variance:

Sum of the difference squared between each value and the mean, multiplied by its probability. So

$V^2(X) = 0.25(-1-0.25)^2 + 0.25(0 - 0.25)^2 + 0.5(1 - 0.25)^2 = 0.6875$

The variance of the distribution is of 0.6875.

The main purpose of the passage is to shift the focus of a debate.

What is meant by debate?

A debate is a procedure that entails formal dialogue about a certain issue, frequently with the participation of a moderator and an audience. Arguments are presented during a debate for frequently divergent points of view. In the past, debates have taken place in public gatherings, educational settings, debating rooms, coffee shops, competitions, and legislative assemblies. In addition to its traditional associations with academic institutions and debating groups, a debate has also been used for recreational and instructional purposes. These debates place a strong focus on logical coherence, factual precision, and audience appeal. Rules permitting participants to discuss and choose the debate's structure are also included in contemporary forms of competitive debate (how the debate will be judged).
