Answer 1

Answer:

(i) Number of people that like both tea and coffee = 10

(ii) Number of people that don't like tea = 10

(iii) Number of people that don't like coffee = 25

Explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of people at the party = 45

Number of people that like tea = 35

Number of people that ONLY like tea = 25

Number of people that like coffee = 20

Number of people that ONLY like coffee = 10

2.  Find the number of people who:

(i) like both tea and coffee.

Number of people that like both tea and coffee = Number of people at the party -   Number of people that ONLY like tea  - Number of people that ONLY like coffee

Number of people that like both tea and coffee = 45 - 25 - 10

Number of people that like both tea and coffee = 10

(ii) do not like Tea.

Number of people that don't like tea = Number of people at the party - Number of people that like tea

Number of people that don't like tea = 45 - 35

Number of people that don't like tea = 10

(iii) do not like coffee

Number of people that don't like coffee = Number of people at the party - Number of people that like coffee

Number of people that don't like coffee = 45 -20

Number of people that don't like coffee = 25
