Textbook Problem

Highway Safety Exercises 41–50 are based on the following table, which shows crashworthiness ratings for several categories of motor vehicles.¹⁰ In all of these exercises, take X as the crash-test rating of a small car, Y as the crash-test rating for a small SUV, and so on, as shown in the table.

		Overall Frontal Crash Test Rating
	Number Tested	3(Good)	2(Acceptable)	1(Marginal)	0(Poor)
Small Cars, X	16	1	11	2	2
Small SUVs, Y	10	1	4	4	1
Medium SUVs, Z	15	3	5	3	4
Passenger Vans, U	13	3	0	3	7
Midsize Cars, V	15	3	5	0	7
Large Cars, W	19	9	5	3	2

Compute $P\left(X\ge 2\right)$, and interpret the result.
