Answer:
The probability that the result of one die roll is greater than 4 is the number of events in set A divided by the total number of possible outcomes (the size of the sample space S) and so the probability of getting a number greater than 4 on one die roll is 2/6 which reduces to 1/3 .
Step-by-step explanation:
Assuming you mean “greater”, rather than “greater than or equal to”, the “successful” rolls are 5 and 6. That’s two out of six choices, so the probability is 2/6 or 1/3.
It gets more interesting when you want the total of several dice to be above a certain number, or to get that number on M of N dice rolls.
But the two basic probability formulas work - 1) add up all possible successful results and all possible results, then divide the number of successes into the total. 2) Multiply all the failure probabilities together, then subtract the result from 1 (100%) to get the success probability. With these two rules, you can solve most simple probability problems.
Playing D&D, and want to know the chance of scoring a 17 or 18 total when rolling 3 dice? You can only get an 18 one way - 6 6 6. You can get a 17 three ways - 6 6 5, 6 5 6, or 5 6 6. So that’s 4 chances out of 6 x 6 x 6 possibilities, which is 216. That’s about 1.85%. With quite a bit more work, you can discover the chance of getting a 17 or better when rolling 4 dice and adding the 3 highest.
Three pairs of shoes cost $108. If each pair costs the same, how much does each one cost?
A.$32
B.$34
C.$36
D.$38
Answer:
C: 36
Step-by-step explanation:
There are 3 pairs of shoes. They all cost the same. Since these shoes add up to 108 dollars, they basically multiply by three to get to 108. (3x=108) If you want to figure out the cost of one shoe you just have to reverse the process by using division. So just do simple division by dividing 108 by three (108/3=x) and there is your answer, 36.

Answer:
∠x = 36°
Step-by-step explanation:
∠a = 180° - 106° = 74°
=> ∠b = 180° - 40° - 74° = 66°
=> ∠c = 180° - 66° = 114°
=> ∠d = 180° - 114° - 30° = 36°
=> ∠x = ∠d = 36°
Tapanga drew triangle XYZ on her paper the measure of angle X was 80 degrees angle y was congruent to angle Z what was measure of angle Z
Answer:
50degrees
Step-by-step explanation:
The sum of angle in the triangle XYZ is 180degrees, hence;
<X + <Y + <Z = 180
Given
m<X = 80degree
m<Y = m<Z
Required
m<Z
Substitute the given angle
80 + m<Z + m<Z = 180
80 + 2m<Z = 180
2m<Z = 180 - 80
2m<Z = 100
m<Z = 100/2
m<Z = 50degrees
Hence the measure of angle Z is 50degrees

The value of y varies directly with x. When y=75, x= 0.5. What is the value of y when x is 2.25?
Even though I pulled up the work, I still don’t know what to do ♀️
Answer:
y=337.5 when x = 2 1/4
Step-by-step explanation:
Well first we want to know what's the function here
How do we get y to be 75 if x is .5?
75/.5 is 150
so can we say the function is 150x=y
Now lets plug
2 1/4 or 2.25 for x
2.25*150 = 337.5
y=337.5 when x = 2 1/4

The ratio of mango ice cream to strawberry ice-cream is 1:4. Total no. of ice cream is 30. What is the no. of mango ice-cream?
Step-by-step explanation:
let the ratio of ice cream be x&4x
total number of ice cream =30
now,
x+4x=30
5x=30
x=30/5
x=6
mango ice cream=x=6
strawberry ice cream=4x=4×6=24
hope it helps.
Answer:
6 !
Step-by-step explanation:
mango = x
strwberry = 4x
total = x+4x = 5x = 30
5x= 30
x= 30/5 = 6
mango = x= 6
strwberry = 4x = 24
I hope im right!

A city council consists of sevenseven Democrats and eighteight Republicans. If a committee of fivefive people is selected, find the probability of selecting twotwo Democrats and threethree Republicans.
Answer:
The probability of selecting two Democrats and three Republicans is 10.7%.
Step-by-step explanation:
Given that a city council consists of seven Democrats and eight Republicans, if a committee of five people is selected, to find the probability of selecting two Democrats and three Republicans the following calculation must be performed:
7 = 100
2 = X
2 x 100/7 = X
28.57 = X
8 = 100
3 = X
3 x 100/8 = X
37.5 = X
0.2857 x 0.375 = X
0.107 = X
0.107 x 100 = 10.7
Therefore, the probability of selecting two Democrats and three Republicans is 10.7%.

He sum of seven interior angle measurements in an octagon equal 845º. What is the angle measurement of the 8th angle?
Answer: [tex]235^{\circ}[/tex]
Step-by-step explanation:
Given
The Sum of the seven interior angles of an octagon is [tex]845^{\circ}[/tex]
for a Polygon, the sum of the interior angles is given by [tex](n-2)180^{\circ}[/tex]
for octagon, n=8
The Sum of interior angles is [tex](8-2)360^{\circ}=1080^{\circ}[/tex]
Suppose the eighth angle be [tex]x[/tex]
[tex]\therefore x+845=1080\\\Rightarrow x=235^{\circ}[/tex]
The [tex]8^{th}[/tex] angle is [tex]235^{\circ}[/tex]

What single percentage change is equivalent to a 11% decrease followed by a 15% decrease?
Answer:
Read the explanation to find your answer.
Step-by-step explanation;
First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100.
Answer:
The answer is 75.65%.
Step-by-step explanation:
Since we are decreasing the percentages, we will first take 100 and subtract 11% from it, which is 89%. Now take 15% and turn it into decimal form, and we get 0.15. Then multiply 0.15 by 89 and we get 13.35. Now we have our number 13.35, we will subtract 89 from 13.35, and we get 75.65%. Therefore, the answer is 75.65%.

You use 7 1/2 c flour to make 3 loaves of bread. The second person uses the same recipe. He will make b loves of bread using f cups of flour. Write an equations that represents of the relationship between b and f.
Answer:
b = 2/5f
Step-by-step explanation:
Cups of flour = loaves of bread
7 1/2 c = 3
c = 3 ÷ 7 1/2
c = 3 ÷ 15/2
= 3 × 2/15
= 6/15
= 2/5
c = 2/5
Cups of flour = loaves of bread
2/5 f = b
b = 2/5f
