1. Determine the odds in favour of randonmy selecting a person in Edmonton that only owns a road bike

 

 

2. Determine the odds against owning a mountain bike

Answer 1

Hi Layne

 

You need to figure out percents that add to 100% and then you can solve this

 

so

 

Road bike only = 48 -15  = 33%

 

Mountain bike only = 59 -15 = 44%

 

both                      = 15%

 

neither                   = 8%

 

so for #1

 

Prob = 33%

 

for #2 the odds against owning a mountain bike would be road bike only or neither

 

Prob = 41%

 

Hope this helps
