Correct question: Find the number of students in the set FΔBΔM
Answer:
FΔBΔM = 130
Step-by-step explanation:
In set notation the symbol Δ means symmetric difference. The symmetric difference of two or more sets is the combination or union of the elements of the sets excluding their interception.
in the question the following are given;
n(F∩B∩M)=10
n(F∩B)=36
n(F∩M)=20
n(B∩M)=18
n(F)=65
n(B)=76
n(M)=63
From the attached Venn diagram,
FΔBΔM= 35+32+19+26+10+8
FΔBΔM= 130
It has a 31% chance. i used a calculator. so i guess the best answer is B.
