Question

At the Rowlett Holiday Parade

there were a total of 51 floats. If
7 of those floats were from
sports teams, what percent
were NOT sports teams?

Answer 1

`p =(7)/(51)= 0.1372`

And then the probability that is NOT from sport temas using the complement rule is given by:

`q = 1-p =1- (7)/(51)= 0.8627`

And if we convert that into % we got:

`0.8627 *100= 86.27\%`

Approximately 86.27% of the floats were NOT sports teams

Explanation:

For this case we can begin finding the % of floats that were from sport tems using the Laplace definition of probability given by:

`p = (Possible)/(Total)`

And replacing we got:

`p =(7)/(51)= 0.1372`

And then the probability that is NOT from sport temas using the complement rule is given by:

`q = 1-p =1- (7)/(51)= 0.8627`

And if we convert that into % we got:

`0.8627 *100= 86.27\%`

Approximately 86.27% of the floats were NOT sports teams
