Matt conducted a survey to determine his classmates' favorite baseball team. After polling 50 classmates Matt arranged a table. What fraction of the people that Matt surveyed named the Philadelphia Phillies or the Pittsburgh Pirates as their favorite team?

Atlanta Braves 8

Colorado Rockies 1
L.A. Dodgers 2
New York Mets 7
Philadelphia Phillies 3
Pittsburgh Pirates 7
Boston Red Sox 6
Texas Rangers 8

What did you get?

How can anything have two values?

This isn't a difficult problem. You have 50 students and __ named the Philadelphia Phillies. So that would make it __/50. Now fill in the blank and do the second one.

The question is "What fraction of the people that Matt surveyed named the Philadelphia Phillies or the Pittsburgh Pirates as their favorite team?" This is equal to the fraction that picked the Phillies + the fraction that picked the Pirates.

Or... or...

Percentage stats are generally expressed in percentage of 100. The sample group is only fifty.

Double the sample group to 100... double the team selections represented... and you have the favorites percentage, too. :eek:

That may not be showing the math the instructor wanted but the results are the same... :cool:

It's quite simple: of the 50 people surveyed, how many of them named either the Phillies or the Braves as their favorite team?

Philadelphia Phillies 3
Pittsburgh Pirates 7

How does that become percentages or fractions?

s_cianci, are you using 50 as the common denominator?
*edit* 3/50 and 7/50 - yes?
