The probability for rolling a sum of 7 is: 1/6
Step-by-step explanation:
Given that two six-sided dies are rolled the total outcomes will be:
![6*6 =36](https://tex.z-dn.net/?f=6%2A6%20%3D36)
n(S) = 36
Out of total outcomes we have to count the outcomes that sum up to 7
Let A be the event that the sum of outcomes is 7
![A = \{(1,6), (2,5), (3,4) , (4,3) , (5,2), (6,1)\}](https://tex.z-dn.net/?f=A%20%3D%20%5C%7B%281%2C6%29%2C%20%282%2C5%29%2C%20%283%2C4%29%20%2C%20%284%2C3%29%20%2C%20%285%2C2%29%2C%20%286%2C1%29%5C%7D)
Here the first number is the result of first die and second number is the result of 2nd die.
n(A) = 6
So the probability of A will be:
![P(A) = \frac{n(A)}{n(S)}\\\\=\frac{6}{36}\\\\=\frac{1}{6}](https://tex.z-dn.net/?f=P%28A%29%20%3D%20%5Cfrac%7Bn%28A%29%7D%7Bn%28S%29%7D%5C%5C%5C%5C%3D%5Cfrac%7B6%7D%7B36%7D%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B6%7D)
Hence,
The probability for rolling a sum of 7 is: 1/6

Answer:
the price of the shoes is $20
Step-by-step explanation:
According to the question, The computation of the price of the shoes is shown below:
Data provided in the question
0.05x = 1
Based on the above information
We now solve for x
x = 1 ÷ 0.05
It can be written as
= 100 ÷ 5
= $20
hence, the price of the shoes is $20
Answer:
3 times the height of the cylinder
Step-by-step explanation:
Since he volume of a cone is 1/3 of the volume of a cylinder or the volume of the cylinder is 3 times the volume of the cone, the cone needs to have a height 3 times the height of the cylinder so they both have the same volume
X= 96
Y=84
a straight line equals 180 so you just subtract that number from it for X, for Y the diagonal number is equal so its just the same as the one acrossed from it
