Answer:


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
