Draw a line under the thesis statement in the paragraph below. Replace it with a new thesis statement that clarifies the writer's theme. Starfish are marine invertebrates. Sometimes sea waves roll rocks on top of the starfish, damaging an arm. In other cases, the starfish sheds an arm if it is attacked by a predator. The starfish sacrifices the arm as a way of escaping from the predator. As the new arm grows to full size, which takes several weeks, the other arms are used for feeding and moving.

An um contains three red balls, four white balls, and two black balls. Three balls are drawn from the um at random without replacement. For each red ball drawn, you win $10, and for each black ball drawn, you lose$15. Let X represent your net winnings. (a) Compute P(X = 0). (b) Compute P(X < 0). (c) Compute E(X), your expected net winnings.
