Answer:
the probability that a person drinks root beer given that they are over 40 is 2/17.
Explanation:
To find the probability that a person drinks root beer given that they are over 40, we need to look at the table provided. According to the table, the number of people who drink root beer and are over 40 is 30.
The total number of subjects is given as 255.
Therefore, the probability can be calculated as:
Probability = Number of favorable outcomes / Total number of possible outcomes
In this case, the number of favorable outcomes (people who drink root beer and are over 40) is 30, and the total number of possible outcomes (total number of subjects) is 255.
So, the probability of a randomly selected person drinking root beer given that they are over 40 is:
Probability = 30 / 255
This can be simplified by dividing both the numerator and denominator by 15:
Probability = 2 / 17
Therefore, the probability that a person drinks root beer given that they are over 40 is 2/17.
Good luck!
