The probability of a given event gives a result of 0.00037. It is generated by applying the basic concepts of probability to the assigned problem.
What is probability?
Probability depicts the number of possibilities of how many times an event can occur. The probability of happening of an event invariably lies between 0 and 1. For a sure event, it is always 1. Its formula is given as P(E) = No. of favourable outcomes / Total no. of outcomes
Calculation of finding the probability according to the conditions specified
The entire number of cards in a standard deck = 52
Total number of favourable outcomes = 1
The probability of selecting two cards is given by P(E1) which is equal to 1 / 52
P(E1) = 1 / 52
Another card is selected without replacing the first card, so the total number of cards in the deck becomes 51. The probability of selecting a card from these 51 cards is given by P(E) i.e. (1 / 52) × (1 / 51)
P(E) = 1 / 2652
P(E) = 0.00037
Hence, the required probability is given by 0.00037.

Bashir is the youngest of four siblings whose ages are consecutive integers. If the sum of their ages is 66, find Bashir's age.
Answer:
15
Step-by-step explanation:
x+x+1+x+2+x+3=66
simplify into 4x+6=66
subtract 6 from both sides to get 4x=60
divide both sides by 4 to get x=15
The age of Bashir is 15 years.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let the consecutive age be x, x+1, x+2 and x+3.
Now, sum of their ages is 66
So, x+ x+1 + x+2 + x+3 = 66
Simplifying for x, we get
4x+6=66
subtract 6 from both sides
4x=60
divide both sides by 4
4x /4 = 60/4
x= 15
Hence, Bashir age is 15 years.

A foreign exchange student from Denmark would like to buy gifts for her family. She finds a special deal, 7 t-shirts for $90.93, that she would like to purchase for her family. However, her family only consists of 5 people. If she wants to purchase 5 t-shirts for her family members at that special rate, what would be the cost of these t-shirts in her currency of Krona? (Currency conversion rate is 1 U.S. Dollar = 8.6964 Krona)
Using proportions, it is found that the cost of the 5 t-shirts would be of 564.83 Kronas.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three, that can be either direct(cross multiplication) or inverse(line multiplication), deriving from proportional relationships. One example of application of proportions is for currency conversion problems, as multiplication or division operations are applied according to the rates of each coin.
For this problem, we have that 7 t-shirts cost $90.93, hence the cost of a t-shirt in U.S. dollars is given applying the proportion to find the unit rate as follows:
$90.93/7 = $12.99.
The cost of 5 t-shirts will be given by:
5 x 12.99 = $64.95.
Applying the proportion 1 U.S. Dollar = 8.6964 Krona, the cost in Kronas is:
64.95 x 8.6964 = 564.83 Kronas.
The cost of the 5 t-shirts would be of 564.83 Kronas.

Katie invested a total of $8000 part at 5% simple interest in part at 6% simple interest. at the end of one year the investments had earned $454 interest. how much was invested at each rate?
If Katie invested a total of $8000, part at 5% simple interest and part at 6% simple interest and at the end of one year the investments had earned $454 interest, then she invested $2600 at 5% and $5400 at 6% simple interest
Given,
The total invested amount = $8000
Consider the amount invested at 5% simple interest as x and the amount invested at 6% simple interest as y
Then, the equations will become
x + y= 8000
x = 8000-y
At the end of one year the investment = $454
0.05x + 0.06y =454
Substitute the value of x in the equation
0.05(8000-y) + 0.06y =454
400-0.05y+0.06y =454
0.01y+400=454
0.01y =54
y = 5400
Substitute the value of x in
x + y = 8000
x+5400=8000
x=8000-5400
x=2600
Hence, if Katie invested a total of $8000, part at 5% simple interest and part at 6% simple interest and at the end of one year the investments had earned $454 interest, then she invested $2600 at 5% and $5400 at 6% simple interest

The equation will be: 4.65r + 4.95p = 874.80
The total cost of gas will be sum of the individual costs of both the types of gas. Firstly, calculating cost of regular and premium gas followed by forming the equation.
The total cost of regular gas = Amount of regular gas × Cost of regular gas per gallon
The total cost of regular gas = 4.65 × r
The total cost of premium gas = Amount of premium gas × Cost of premium gas per gallon
The total cost of regular gas = 4.95 × p
We are given overall spending = 874.80
Forming the equation -
Total cost of regular gas + total cost of premium gas = overall spending on gas
4.65r + 4.95p = 874.80
Hence, the equation that models the situation is 4.65r + 4.95p = 874.80.

In a heptagon, the sum of all seven angles is 900 degrees. If you add up the four given angles you will get 600 degrees. In the question it says, "the remaining interior angles are EQUAL" so therefore, the only way to get from 600 to 900 from the remaining three angles is 100. Each remaining angle is 100 degrees
Answer:
Heptagons are known to have seven interior angles that add up to 900°, so we must find the last 3. First, add the first four they gave us.
[tex]160\circ + 130\circ = 290\circ\\= 290\circ + 170\circ + 140\circ\\170\circ + 140\circ = 310\circ\\= 290\circ + 310\circ\\= 600\circ[/tex]
We now know that the remaining angles are all 100°, because the question mentions the rest of the interior angles being equal. The only reasonable 3 equal numbers to add up to 900° would be three 100s in this case.
