Probability are important information when applying descriptive statistics. Probability is the branch of mathematics concerning numerical descriptions. the correct option is (B).
What is probability?Descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur.
here, we have,
A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written as 0.5 or 50%).
The probability formula defines the likelihood of the happening of an event. It is the ratio of favorable outcomes to the total favorable outcomes. The probability formula can be expressed as,
Probability formula:
P(A) = Probability(Event) = Favorable Outcomes/Total Outcomes
P(A) = x/n
where,
P(B) is the probability of an event 'B'.
n(B) is the number of favorable outcomes of an event 'B'.
n(S) is the total number of events occurring in a sample space
Descriptive statistics are brief informational coefficients that summarize a given data set, which can be either a representation of the entire population or a sample of a population. Descriptive statistics are broken down into measures of central tendency and measures of variability (spread). Measures of central tendency include the mean, median, and mode, while measures of variability include standard deviation, variance, minimum and maximum variables, kurtosis, and skewness.
The main purpose of descriptive statistics is to provide information about a data set. In the example above, there are hundreds of baseballs players that engage in thousands of games. Descriptive statistics summarizes the large amount of data into several useful bits of information.

If a person with an hourly pay of $9.50 per hour gets a 20$ raise, what is the new hourly pay?
Percent formula, show your work
======================================================
Work Shown:
20% of $9.50 = 0.20*9.50 = 1.90
You earn an extra $1.90 on top of the $9.50 already there. So the new wage is 9.50 + 1.90 = 11.40 dollars per hour
-----------
Shortcut:
1.20*9.50 = 11.40
Think of 1.20 as 100% + 20% = 1 + 0.20 = 1.20, and this represents an increase of 20%
Arianna buys computer games from an online store. each game she orders costs $22 and shipping for her total is $9. arianna can spend no more than $75. how many computer games can arianna buy?
There are 3 computer games she can brought at $75.
Unitary method
Unitary method is defined as the process of finding the value of a unit and then the value of a required number of units.
Given,
Arianna buys computer games from an online store.
Each game she orders costs $22 and shipping for her total is $9.
Arianna can spend no more than $75.
Here we need to find how many computer games did Arianna Brought.
Let x be the number of computer games she brought.
We know that,
Cost for one game = $22
Shipping cost = $9.
She spent = $75.
So, it can be written as,
=> 22x + 9 = 75
=> 22x = 75 - 9
=> 22x = 66
=> x = 66/22
=> x = 3.
So, she can brought 3 computer games at $75.

If we know the distance of an object from earth, we can determine the size of the object by measuring its parallax. True or false?.
False, If we know the distance of an object from earth, we can determine the size of the object by measuring its parallax.
The size of an object can be calculated by measuring its parallax if we know how far it is from Earth. According to the heliocentric theory of the universe, Earth is the center of the universe, and everything else revolves around it. A planet's speed is unaffected by the location of the planet within its orbit.
