Answer 1

Answer: 29

The percent sign is already taken care of, so you'll just input the numeric part only to fill in the green box.

========================================================

Step-by-step explanation:

Focus on the first row only. This is because we are 100% certain that the person ordered a hot beverage based on the keyword "given".

There are A = 22 who ordered a large hot drink out of B = 5+48+22 = 75 who ordered a hot beverage.

The probability we're after is therefore A/B = 22/75 = 0.29 = 29% approximately.
