Answer:
P(Music/Drama)= [0.25]
Step-by-step explanation:
Given:
From the Table given we can calculate Total Number of Students.
[tex]\therefore \textrm{Total Number of Student} = \textrm{Total Number of Student in Sophomore grade} +\textrm{Total Number of student in Juniour grade}+\textrm {Total of Student in Senior grade}\\\textrm {Total Number of Student}= 30+35+35 =100[/tex]
From the Table given we can calculate Total Number of Students in Music\Drama
[tex]\therefore \textrm{Total Number of Student in Music/Drama} = \textrm{Total Number of Student in Sophomore grade} +\textrm{Total Number of student in Juniour grade}+\textrm {Total of Student in Senior grade}\\\textrm {Total Number of Student in Music/Drama}= 7+13+5 =25[/tex]
Now by the formula of Probability.
[tex]P(E) =\frac{\textrm{Number of possible outcomes}}{\textrm{Total Numbber of Outcomes}}[/tex]
Probability for Music/Drama
[tex]P(Music/Drama) =\frac{\textrm{Total Number of Student in Music/Drama}}{\textrm{Total Number of Students}}[/tex]
[tex]\therefore P(Music/Drama)=\frac{25}{100} =0.25[/tex]
