A two-way frequency table is shown below that displays the relationship between age and preferred soft drink. We took a sample of 100 people and recorded the following results:

Cola Rootbeer Dr. Fizz Total

10-25 years 10 5 20 35

26-40 years 15 10 10 35

41-55 years 20 10 0 30

Total 45 25 30 100

What is the probability (rounded to the nearest whole percent) that a randomly selected person is 10 to 25 years old or prefers drinking rootbeer?

AGE Cola Rootbeer Dr. Fizz Total

10-25 years 10 5 20 35

26-40 years 15 10 10 35

41-55 years 20 10 0 30

Total 45 25 30 100

Probability that a randomly selected person is 10-25 years old or prefers drinking rootbeer

Probability of 10-25 years old = 35/100 = 35%

Probability of drinking rootbeer = 25/100 = 25%

Probability of 10-25 years or perfers to drinking rootbeer

= 35% + 25% = 60% 1st option
