Explanation / Answer

23.

The average no.of children who contract the flu after get their vaccinated is 3 cases per 1000 children
then lambda = 3
POSSION DISTRIBUTION
pmf of P.D is = f ( k ) = e- x / x!
where
= parameter of the distribution.   
x = is the number of independent trials
I.
mean =
= 3

probability that none of 1000 children will contract flu this season
P( X = 0 ) = e ^-3 * 3^0 / 0! = 0.0498

Answer:
option :B
