Question 361312: I'm working on my statistics homework and need help with a few questions.
This is the information provided:
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) = 0.32 and P(B) = 0.34
1.Say in plain language what the event “A or B” is.
2. If C is the event that the person chosen has normal weight or less, what is P(C)?
For question #1 I submitted:
Probability of Disjoint Events
P(A or B) = P(A) + P(B)
.32 + .34= .66
dependent events:
P(either A or B happens) = P(A happens) + P(B happens)
For question #2 I submitted:
1 – .66 = .34
P(C)= .34
Is this correct? Please help!

You can put this solution on YOUR website! Define two events:
P(either A or B happens) = P(A happens) + P(B happens)
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) = 0.32 and P(B) = 0.34
1.Say in plain language what the event “A or B” is.
2. If C is the event that the person chosen has normal weight or less, what is P(C)?
For question #1 I submitted:
Probability of Disjoint Events
P(A or B) = P(A) + P(B)
.32 + .34= .66
dependent events:

Comment on your answer to #1. I think they want
you to give the answer "in plain language".
=================================================
For question #2 I submitted:
1 – .66 = .34
P(C)= .34

Comment on your answer to #2.
Correct.
