National Coffee Dr-inking Trends is “the publication” in the coffee industry. Each year it tracks consumption patterns in a wide variety of situations and categories and has done so for over five decades. A recent edition says that 39% of the total coffee drinkers age 18 years and over have purchased shade-grown coffee in the last year.
If this percentage is true for coffee drinkers at Crimson Light’s coffeehouse, what is the probability that of the next 50 customers purchasing coffee at Crimson Light’s,
a. more than 20 will ask for a shade-grown variety?
b. fewer than 15 will ask for a shade-grown variety?
