Step-by-step explanation:
Given: The proportion of patients experience injection-site reactions with the current needle : p=0.11
Sample size : n= 4

Binomial probability formula: 
The required probability : P(x=0)

Hence, the probability that none of the 4 people get an injection-site reaction = 0.6274
