The two dice are rolled. what is the theoretical chance that they land to form a sum of 11?
Rufina [12.5K]

Answer:

Propability of getting either sum is 2/9

Step-by-step explanation:

Well, we know that there are 36 total arrangements of the two six sided die. So we have a possibility of 3,4 and 4,3. Likewise, we have a possibility of 5,2 and 2,5. We also have a possibility of 1,6 and 6,1. That takes care of the probability That you get two die that add up to 7. Now for 11, you have 5,6 and 6,5. So since you asked for the probability of getting either or, you add all the probabilities, which is 6/36+2/36=8/36=2/9. So the probability of getting either sum is 2/9.

Which represents the reflection of f(x)=sqrt x over the y axis
zloy xaker [14]

reflection of f(x)=\sqrt{x} over the y axis we get g(x)=\sqrt{-x}

Step-by-step explanation:

We need to find the reflection of f(x)=sqrt x over the y axis

So, reflection over y- axis

If the function f(x) is transformed over y-axis then the new function g(x) will be g(x)= f(-x)

So, finding reflection of f(x)=\sqrt{x} over the y axis we get:

g(x)=\sqrt{-x}

So, reflection of f(x)=\sqrt{x} over the y axis we get g(x)=\sqrt{-x}

Kylie correctly understood that it is a difference of squares, but she did not determine the product correctly.
