You would expect to roll a 6 approximately 20 times in 120 rolls. This is because, on average, in the long run, you would expect a specific outcome (in this case, rolling a 6) to occur with a frequency proportional to its probability (1/6) over a large number of trials (120 rolls).
When rolling a fair 6-sided number cube, each of the six faces has an equal probability of landing face up. The probability of rolling a 6 on a fair 6-sided number cube is 1/6.
To find out how many times you would expect to roll a 6 in 120 rolls, you can use the probability formula:
Expected number of successful outcomes = Probability of success * Total number of trials
Expected number of times to roll a 6 = (1/6) * 120
Expected number of times to roll a 6 = 20

A bag of marbles contains 12 red marbles 8 blue marbles and 5 green marbles. If three marbles are pulled out find each of the probabilities. Find the probability of pulling three green marbles out with replacement
[tex] |\Omega|=25\cdot24\cdot23=13800\\

The expression 5(F-32) divided by 9 yes the Celsius temperature for a Fahrenheit temperature of F degrees C noon Fahrenheit temperature in Centerville was 86° what was the temperature in degrees Celsius
Answer:
30°C
Step-by-step explanation:
The following expression can be used to convert Farenheit degrees (°F) to Celsius degrees (°C).
°C = 5 . (°F - 32) / 9
If the temperature in Centerville is 86°F, we can replace this value in the previous expression to find its value in the Celsius scale.
°C = 5 . (°F - 32) / 9
°C = 5 . (86 - 32) / 9
°C = 5 . (54) / 9
°C = 270 / 9
°C = 30°C

A right rectangular prism is shown. What shape best describes the cross section cut perpendicular to the base of a right rectangular prism? Parallelogram Trapezoid Rectangle Square
The shape that best describes the cross-section cut perpendicular to the base of a right rectangular prism is a rectangle.
A cross-section cut perpendicular to the base of a right rectangular prism will always result in a rectangular shape.
This is because a rectangular prism has six faces, and the base of the prism is one of those faces.
When you make a cross-section cut perpendicular to the base, you are essentially slicing through the prism parallel to one of its other faces.
Since the base is a rectangle, the cross-section will also be a rectangle.
In summary, the cross-section cut of a right rectangular prism perpendicular to its base will consistently yield a rectangular shape due to the inherent geometry of the prism.

Answer:
[tex]78\ million=7.80\times 10^7[/tex]
Step-by-step explanation:
A number N can be written in scientific notation as :
[tex]N=p{\circ}0\times 10^q[/tex]
Where
p is the any real number
q is any integer
Here, the given number is 78 million. Firstly, we must know meaning of 1 million.
Since, [tex]1\ million=10^6[/tex]
[tex]78\ million=78.0\times 10^6[/tex]
To convert the above number in scientific notation, we can shift the decimal before 8 such that,
[tex]78\ million=7.80\times 10^7[/tex]
Hence, this is the required solution.

Two positive numbers have a difference of four and a product of 96 what are the numbers
Answer:
The two positive numbers are 12 and 8.
Explanation:
The first phrase in the sentence tells us the difference between numbers equals 4, which can be represented a - b = 4
The second phrase tells us when multiplied together, it equals 96, which can be represented by the ab = 96, or a(b) = 96
So, first step is to list the factors of 96. I prefer to list them as pairs:
1, 96; 2, 48; 3, 32; 4, 24; 6, 16; and 8, 12
Now we plug each these pairs into the first equation to see if they satisfy the equation.
96 - 1 = 95 24 - 4 = 20
95 > 4 20 > 4
48 - 2 = 46 16 - 6 = 10
46 > 4 10 > 4
32 - 3 = 29 12 - 8 = 4
29 > 4 4 = 4
Because a = 12 and b = 8 satisfies both equations that represent the given sentence, the two positive numbers are 12 and 8.
