The Deep Dive

Let’s break this down in a fun way! To find out how many people drink tea in the morning, you can simply add those who drink tea only (40) to those who drink both tea and coffee (80). So, that’s 40 + 80 = 120 people who drink tea in the morning!
As for coffee, you do the same—those who drink coffee only (44) plus those who drink both tea and coffee (80). So, 44 + 80 equals 124 coffee drinkers!
Lastly, to find out how many people drink neither tea nor coffee, subtract everyone who drinks either beverage from the total number of people surveyed. That’s 236 - (120 + 124) = -8. Oops! Looks like someone had a miscalculation, as negative people don’t exist. Check the numbers again!
