Question

suppose 25 out of 175 people said they like to play disc golf and out 5 out of every twelve of the players have a personalized black disc at the Staybridge in a group of 252 people predict how many you would expect to have a personalized flying disc

Answer 1

We have
`(5)/(12)` of 252 people who have a personalized black disc

Number of people who would have personalized flying disc =
`(5)/(12)*252= (2*252)/(12)=105` people

Then we work out the number of people who like to play disc golf:

`(25)/(175)*105= (25*105)/(175)=15` people

So we have 15 people who like to play disc golf and have personalised black disc.
