Answer:
65%
Step-by-step explanation:
No, the events "drank coffee" and "drank tea" are not mutually exclusive, as there are 10% of employees drank both coffee and tea.
If there are 50% drank coffee and 10% of them enjoy both, then there are 40% of the employees enjoy only coffee.
Similarly, there are 15% of employees who only enjoy tea.
Then the probability of selecting a person who only enjoy tea or coffee is
40% + 15% = 65%
