This week, a 29 year old man, a 37 year old woman, a 19 year old man, and a 67 year old man are chosen.

1) What is the probability that all four participants are not obese?

2) What is the probability that exactly one of the men under 65 is obese?

3) What is the probability that at least one of the three people chosen for weigh in is obese?

Explanation / Answer

1)probability that all four participants are not obese =(1-0.23)*(1-0.21)*(1-0.24)*(1-0.19)=0.3745

2)probability that exactly one of the men under 65 is obese =29 year old man is obese and 19 year old man not+

19 year old man is obese and 29 year old man not=0.23*(1-0.24)+(1-0.23)*0.24=0.3596
