a total participants
b attended a session on cybersecurity,
c attended a session on cloud computing.
If exactly d participants attended neither session
a-d=b+c-x
x=b+c+d-a
x/a=(b+c+d-a)/a
answer is c

Use table method.
Total-= a
Total who participated in Cyber one= b
those who didnt= a-b
total who participated in cloud one- c
those who didnt- a-c
THose who did in neither = d
Thus those who did in cloud one but not cyber = a-b-d
Those who did in both = C - (a-b-d)
= c-a+b+d
fraction of total participants
= (b+c+d-a)/a
option c
Total-= a
Total who participated in Cyber one= b
those who didnt= a-b
total who participated in cloud one- c
those who didnt- a-c
THose who did in neither = d
Thus those who did in cloud one but not cyber = a-b-d
Those who did in both = C - (a-b-d)
= c-a+b+d
fraction of total participants
= (b+c+d-a)/a
option c

At a tech seminar with a total participants, b attended a session on cybersecurity, and c attended a session on cloud computing. If exactly d participants attended neither session, then in terms of a, b, c, and d, what fraction of the participants attended both sessions?
Total participants= a
People who attended Cybersecurity Session= b
People who attended session on cloud computing= c
People who attended neither session = d
People who attended Cloud computing session but not Cybersecurity = a-b-d
People who attended both session= c-(a-b-d)= c-a+b+d
Fraction= (c-a+b+d)/a
C
Total participants= a
People who attended Cybersecurity Session= b
People who attended session on cloud computing= c
People who attended neither session = d
People who attended Cloud computing session but not Cybersecurity = a-b-d
People who attended both session= c-(a-b-d)= c-a+b+d
Fraction= (c-a+b+d)/a
C
