**Chapter 5 Assessment**

1. **Determine whether the given values can be looked upon as the values of a probability distribution of a random variable that can take on the values 1, 2, 3, 4, and 5. Answer yes or no. If no, explain why not.**

a)
- $ f(1) = 0.18 $
- $ f(2) = 0.20 $
- $ f(3) = 0.22 $
- $ f(4) = 0.23 $
- $ f(5) = 0.18 $

2. **The number of monthly breakdowns of a computer is a random variable with an average of 1.6 breakdowns per month. Find the probability that this computer will function for a month with only 1 breakdown.**

3. **If 20 percent of the mice used in an experiment will become very aggressive after having been administered an experimental drug, find the probability that exactly 2 of 6 mice which have been administered the drug become very aggressive.**

4. **A customs inspector decides to inspect two of 12 shipments that arrive from Madrid by plane. If the selection is random and four of the shipments contain contraband, find the probability that the customs inspector will catch one of the shipments with contraband.**

Expert Solution

Step 1

Let X be the number of shipments with contraband.

Then,

P[X=x] = $\frac{(\begin{matrix} n_{1} \\ x \end{matrix}) \times (\begin{matrix} N - n_{1} \\ n - x \end{matrix})}{(\begin{matrix} N \\ n \end{matrix})}$

Where,

N = population size

n₁ = number of successes in the population

x = number of observed success

n = number of draws
