7. (8 pts.) Imagine you are the casting director of a blockbuster Hollywood movie and need to find a number of background characters so as to have a sufficient diversity of faces in a
certain social scene. The available population of 400 movie extras observes the
following breakdown of physical appearance: 40% have brown hair. 14% have blonde
hair, 26% have black hair, 9% have red hair, and 11% have gray hair. In this same
population, 54% have brown eyes, 19% have green/hazel eyes, 13% have blue eyes, and
14% have eyes of other colors. Assume sampling with replacement and that hair color
and eye color are independent (although genetics say otherwise), oideaop to xlaqua
