In Exercises 3–6, solve the initial value problem x′(t) = Ax(t) for t ≥ 0, with x(0) = (3, 2). Classify the nature of the origin as an arc actor, repeller, or saddle point of the dynamical system described by x′ = Ax. Find the directions of greatest attraction and/or repulsion. When the origin is a saddle point, sketch typical trajectories.

They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king.
