Answer 1

Answer:

50% people like both.

Step-by-step explanation:

Likewise 70% people like tea and 30% people that not like. This 30% people are like only Coffee.

People that's like both = total people how like Coffee - People that's like only Coffee

= 80 - 30 = 50%

People that's like both = total people how like tea - People that's like only tea

= 70 - 20 = 50%
