Anumber from 1 to 11 is chosen at random. what is the probability of choosing an odd number?
a. 1/11
b. 5/11
c. 6/11
d. none of the above

Your answer is C.) 6/11.  Here is why if we look at all the numbers between 1-11 we find 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11.  I bolded the odd numbers.  There are 6 odd numbers and 5 even numbers.  This means that the chance of choosing an odd number is 6/11.  I hope this helped :)

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.
