Choosing at least one even number when selecting 2 cards from the bag
Using the combination formula, it is found that there is a 0.7778 = 77.78% probability of choosing at least one even number.
What is the combination formula?[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this problem, there are 10 numbers numbered from 1 to 10.
The total number of outcomes is given by:
[tex]T = C_{10,2} = \frac{10!}{2!8!} = 45[/tex]
The number of outcomes with only odd numbers is given by:
[tex]O = C_{5,2} = \frac{5!}{2!3!} = 10[/tex]
Hence 45 - 10 = 35 outcomes have at least one even number, so the probability is:
p = 35/45 = 0.7778.

Answer: c: 53/64
Explanation:
edge
The probability is analyzed with the help of statistics. The probability of the person buying cereal once a month through the Venn diagram is given as, 53/64. Thus, option C is correct.
What is the Venn diagram?A Venn diagram is the illustration of the information or the data that are in relation to other data and are represented in the form of circles.
The Venn diagram shows the total number of people who eat breakfast (A) every day, and another set shows people who buy cereals (B).
n (A) = 11 + 53 = 64
n (B) = 53 + 4 = 57
n (AB) = 53
Probability of buying cereals for the person eating breakfast every day:
= P (B/A) = P(AB) / P(A) = n(AB )/ n(A) = 53/64
Therefore, option C. 53/64 is the probability.

Prompt:
Select the correct text in the passage.
Which part of this excerpt from Oliver Twist by Charles Dickens hints that Oliver was not expected to live very long?
[Option #1:] It cannot be expected that this system of farming would produce any very extraordinary or luxuriant crop. [Option #2:] Oliver Twist's ninth birthday found him a pale thin child, somewhat diminutive in stature, and decidedly small in circumference. [Option #3:] But nature or inheritance had implanted a good sturdy spirit in Oliver's breast. [Option #4:] It had had plenty of room to expand, thanks to the spare diet of the establishment; and perhaps to this circumstance may be attributed his having any ninth birth-day at all. [Option #5:] Be this as it may, however, it was his ninth birthday; and he was keeping it in the coal-cellar with a select party of two other young gentleman, who, after participating with him in a sound thrashing, had been locked up for atrociously presuming to be hungry, when Mrs. Mann, the good lady of the house, was unexpectedly startled by the apparition of Mr. Bumble, the beadle, striving to undo the wicket of the garden-gate.

a sample of krypton gas occupies 75.0 ml at 0.40 atm. if the temperature remained constant, what volume would the krypton occupy at 2.00 atm?
At constant temperature, if the pressure of the sample of the krypton gas increases to the given value, the volume decreases to 15mL.
What is Boyle's law?Boyle's law simply states that "the volume of any given quantity of gas is inversely proportional to its pressure as long as temperature remains constant.
Boyle's law is expressed as;
P₁V₁ = P₂V₂
Where P₁ is Initial Pressure, V₁ is Initial volume, P₂ is Final Pressure and V₂ is Final volume.
Given the data in the question question;
Initial volume of the gas V₁ = 75.0mL = 0.075LInitial pressure of the gas P₁ = 0.40atmFinal pressure of the gas P₂ = 2.00atmFinal volume of the gas V₂ = ?Now, we substitute our given values into the expression above to determine the new volume of the krypton gas.
P₁V₁ = P₂V₂
V₂ = P₁V₁ / P₂
V₂ = 0.40atm × 0.075L / 2.00atm
V₂ = 0.03Latm / 2.00atm
V₂ = 0.015L
V₂ = 15mL
Therefore, at constant temperature, if the pressure of the sample of the krypton gas increases to the given value, the volume decreases to 15mL.

Median is the middle data in the list of the given numbers. In the given data set the median gets decreased by the presence of the outlier. Thus, option C is correct.
What is an outlier?An outlier is a data that varies significantly from the other data set, due to some error or measuring variability.
The median of the data without outlier is calculated as:
First, data is arranged in the ascending order: 105, 108, 109, 113, 118, 121, 124
Median = [tex]\rm \dfrac{7 + 1 ^{th}}{2} term[/tex]
= 4th term
= 113
The median of the data with outlier is calculated as:
First, data is arranged in the ascending order: 61, 105, 108, 109, 113, 118, 121, 124
Median = [tex]\rm \dfrac{(\dfrac{8}{2})^{th} + (\dfrac{8}{2} + 1)^{th}} {2}[/tex]

The percentage of people with $300,000 or more increases so substantially across the age groups because older individuals have an edge when it comes to accumulating wealth.
What are the age groups?Simply put, older folks have more money because:
1. They have worked for longer periods of time and are thus anticipated to earn higher incomes and hold higher positions.
2. They have had more time to save and invest their money.
Every age group has a greater ability to save money during their working years. Young individuals just starting out in their jobs are less likely to amass enough money to be worth that much.
