Asked by please help me!
I don't know how to begin this question and it is due tonight. I'm not looking for someone to give me the answer. I just need help with the formula that I use and how do I go about answering this?
Is the formula:
P = P(total subject) / P(OJ drinker over 40)
Question:
If one of the 255 subjects is randomly chosen, what is the probability that the person prefers orange juice, given they are over 40? Round your answer to 3 decimal places.
Water Orange Cola
juice
Under 21 years 40 25 20
21 – 40 years 35 20 30
Over 40 years 20 30 35
255/30 = .118
