Two children of mass 20.0 kg and 30.0 kg sit balanced on a seesaw with the pivot point located at the center of the seesaw. If the children are separated by a distance of 3.00 m, at what distance from the pivot point is the small child sitting in order to maintain the balance? (You must show your full solution steps here. The Scratch Paper is not a substitute for the solution steps.)

Consider the experiment of rolling two fair dies simultaneously.  a. (2 points) What is the sample space of this random experiment? b. (2 points) What is the probability of getting at least one 5? c. (2 points) What is the probability of getting a sum of 6? d. (2 points) Given the sum is 7, what is the probability that at least one die is 5?
