use possion distribution 
 
here probability of person to get injuery of such kind p = 10/100000
n = 4000
mean = m =  np = 4000X(10/100000) = 0.4
 
p(x) = e-m.mx / x!
 
put x = 0,1,2 
 
then add all the values and subtract it from 1 
 
that’s your answer

We can use formula of 
P(r>=n)=1-p(r
So for more than 2 persons
P(r>=2)=1-p(r
            =1-p(0)+p(1)
          since m=0.4
          So,p(r)=(e^-m*m^r)/r!
      P(r>=2)=0.007926
