Patients under 18 years old Patients 19-60 years old Patients over 60 years old 6 4 10 12 What is the probability that a randomly selected appointment is with patients over 60 years old and is for a regular cleaning? Simplify any fractions.

Answer 1

Probability that a randomly selected appointment is with patients over 60 years old and is for a regular cleaning = (5/21)

Step-by-step explanation

The probability of an event is calculated as the number of elements in that event divided by the total number of elements in the sample space.

For this question, we are told to find the probability that a randomly selected appointment is with patients over 60 years old and is for a regular cleaning.

Number of patients that are over 60 years and are for regular cleaning = 10

Total number of patients = 2 + 8 + 6 + 4 + 10 + 12 = 42

Probability that a randomly selected appointment is with patients over 60 years old and is for a regular cleaning = (10/42) = (5/21)

Hope this Helps!!!
