Answer:

c he is your answer dear friend‍♀️‍♀️

Probability that the student drinks soda or coffee regularly is 60%

Option D is correct

Percentage of students that drink soda regularly, P(s) = 40%

Percentage of the students that drink coffee regularly, P(c) = 30%

Percentage of students that drink both coffee and soda regularly,

P(s and c) = 10%

Percentage of students that drink coffee or soda regularly is:

P(s or c) = P(s)  +  P(c) - P(s and c)

P(s or c) = 40  +  30 - 10

P(s or c) = 70 - 10

P(s or c) = 60

Probability that the student drinks soda or coffee regularly is 60%
