Overweight? Although the rules of probability are just basic facts about percents or proportions, we need to be able to use the language of events and their probabilities. Choose an American adult at random. Define two events:
A = the person chosen is obese
B = the person chosen is overweight, but not obese
According to the National Center for Health Statistics, P(A)=0.34 and P(B) = 0.33.
(a) Explain why events A and B are disjoint.
(b) Say in plain language what the event “A or B” is. What is P(A or B)?
(c) If C is the event that the person chosen has normal weight or less, what is P(C)?
