Question

On the last day of a Shakespeare class, my English teacher asked the students which play they liked most. 9 students liked Macbeth best, while 12 students had other favorites.

What is the probability that a randomly selected Shakespeare student likes Macbeth best?

Answer 1

9= Macbeth
12= Had other favorites
Students Altogether= 21
\[\frac{ 9 }{ 21 } Macbeth\]
\[\frac{ 12 }{ 21 } Others\]

Answer 2

\[\frac{ 9 }{ 21 }-\frac{ 12 }{ 21 }= \frac{ -1 }{ 7 }\]
