Question 1146131: The probability is 0.005 that any one person attending a parade on a very hot day will suffer heat exhaustion. Find the probability that 18 out of the 3000 person attending the parade will suffer heat exhaustion using
a) Poisson distribution OR Normal approximation to Poisson distribution.
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
np= lambda for Poisson approximation, so 0.005*3000=15
probability with a poisson parameter of 15 that 18 occur
e^(-15)*15^18/18!
=0.0706
