1. A shipment of 20 cellphones to a store contains 3 that are defective. If the store sells 2 cellphones, find (a) the probability distribution for the number of defectives. (b) the cumulative distribution function for the number of defectives. 2. A random variable $X$ has probability distribution given by $f(x) = \begin{cases} \frac{x^2}{24}, & -2 < x < 4 \\ 0, & \text{otherwise} \end{cases}$ (a) Verify that $f(x)$ is a density function (i.e, $f(x) \ge 0$ and $\int_{-\infty}^{\infty} f(x) dx = 1$). (b) Use $f(x)$ to find $P(0 < X \le 1)$. (c) Find the cumulative distribution function $F(x)$ and use it to find $P(0 < X \le 1)$.

(a) Calculate the magnitude of the average force needed to bring a 950 kg car to rest from a speed of 80.0 km/h in a distance of 120 m (a fairly typical distance for a nonpanic stop). N (b) Suppose instead the car hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Calculate the average force exerted on the car and compare it with the force found in part (a), i.e. find the ratio of the force in part(b) to the force in part(a). (force in part (b) / force in part (a)) We consider the average force as the constant force that would have the same effect as the time-varying actual force. The actual force varies markedly with time during the collision.
