The table below shows the drink preferences for people in 3 different age groups. If one of the 255 subjects is randomly chosen, what is the probability that the person drinks water given they are under 21. Round your answer to 3 decimal places.

Water Orange juice Cola

Under 21 years 40 25 20

21 – 40 years 35 20 30

Over 40 years 20 30 35

Not sure if it is 40/95 = 0.421 and if so, how do you set up the problem? and if not please help me!
