Question
choosing a girl or an A student?
According to health statistics taken to observe obesity in men 6 feet or taller:
A = 250 pounds is overweight
B = 225 pounds is borderline overweight
P(A)= .30
P(B)= 40
12. Explain why these events are mutually exclusive?
13. Say in plain language (basic explanation) what the event "A" or "B" means:
14. Find P (A+B)
15. Let C be the event chosen as normal weight (under 225 pounds) – Find P(C)?
16. In a class survey:
A. 5 students used twitter and Facebook
B. 6 students used Facebook and not twitter
C. 17 students used no Facebook, but used twitter
D. 3 students used no Facebook, no twitter
A.
Create a two way table based on this data:
B. Find the following probabilities:
1. P(Facebook)=
2. P(Twitter)=
3. P(No Facebook)=
4. P(No Twitter)=
17. Is the P(Facebook or Twitter) = to the P(Facebook) + P(Twitter)? Why or Why Not?
