Michelle is rolling two six-sided dice, numbered one through six. What is the probability that the sum of her rolls is 4? A. B. C. D.

The probability that the sum of Michelle's rolls is 4 is 0.083 ∴ P(A)=0.083  

Step-by-step explanation:

Given that Michelle is rolling two six-sided dice, numbered one through six.

To find the probability that the sum of her rolls is 4:

∴ n(s)=36

Let P(A) be the probability that the sum of her rolls is 4

Then the possible rolls with sums of 4 can be written as

n(A)=3

The probability that the sum of her rolls is 4 is given by

=0.083

∴ P(A)=0.083 ∴ the probability that the sum of Michelle's rolls is 4 is 0.083

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
