Employees at an office were surveyed about what types of hot beverages they drank that day. it was found that 50% of them drank coffee and 25% drank tea. the survey showed that 10% of the employees drank both coffee and tea.
for these employees, are events "drank coffee" and "drank tea" mutually exclusive?
choose one yes or no?
find the probability that a randomly selected person from this group drank coffee or drank tea?

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%

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
