Given
of Population is vaccinated
So, Probability of a person being vaccinated is 
and simultaneously , probability of not vaccinated is 
Now, Probability that atleast one of them has been vaccinated is given by
Answer:
Undefined or Infinity
Step-by-step explanation:
(x1,y1)=(-11,8)
(x2,y2)=(-11,-17)
Slope = (y2-y1)/(x2-x1)
= (-17-8)/(-11-(-11))
= -25/0
= Undefined
Seems to be an arythmetic sequence
Sn=[n(a1+an)]/2
where
Sn means sum of all terms up the nth term
n=number of terms
a1=first term
an=nth term
so from 86 to the 22th term is from a1 to a22
find teh sequence
miknus 7 each time
an=a1+d(n-1)
an=87-7(n-1)
find 22n term
a22=87-7(22-1)
a22=87-7(21)
a22=87-147
a22=-60
S22=[22(87-60)]/2
S22=[22(27)]/2
S22=594/2
S22=297
the sum is 297
