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 cost would be $0.10. You would figure this out because 10 cents is a 10th of a dollar
Step-by-step explanation:
Answer: -41h+38k
Step-by-step explanation: -7×7h= -49h
-7×-5k= +35 basically just using the distributive property
Combine like terms: -49h+8h= -41h 3k+35k=38k
You can't combine -41h and 38k because they are not like terms. So, the expression simplifies to -41h+38k or 38k-41h
Answer:
10.85
Step-by-step explanation:
2x + 1.5x x=3.1
simply plugg in <em>3.1 for X</em>
2 multiplied by 3.1 + 1.5 multiplied by 3.1 and you get
6.2 + 4.65 which = 10.85
