The sample must be random and independently selected from the normally distributed population.
n*p and n*q both must be greater than 5
There must be two outcomes "success" and "failure"
The number of trials must be fixed.
From the given information 2), 3)and 4) conditions are satisfied, but not 1) because we are not given that people are selected randomly.
