Someone plzzz HELP me !! :(



Answer :

35/100 which simplifies to 7/20 for English
20/100 which simplifies to 1/5 for Math
12/100 which simplifies to 3/25 for Art
33/100 which simplifies to ~1/3 for Social Studies
so 
art:12
math:20
English:35
Social studies:33
so probility is the disired outcomes over all possible outcomes or Desired/all possible
so add them and get

100
so art is 12/100=3/25
math is 20/100=1/5
english is 35/100=7/20
social studies is 33/100
