Question

question 5 of 5 the pie graph shows the distribution of registered runners, by age group, for a community 5k run. runners from each age group are randomly selected to win door prizes after the race. what are the odds (in age group : not in age group) that the first person called for a door prize is in the age group of 30 - 39 years? a 3:17 b 3:7 c 7:13 d 35:30

Explanation:

Step1: Identify percentage in 30 - 39 group

The percentage of runners in the 30 - 39 age - group is 35%.

Step2: Identify percentage not in 30 - 39 group

The total percentage of runners not in the 30 - 39 age - group is \(100 - 35=65\%\).

Step3: Calculate the odds

The odds of a runner being in the 30 - 39 age - group to not being in the 30 - 39 age - group is \(\frac{35}{65}=\frac{7}{13}\), or 7:13.

Answer:

C. 7:13
