<span>The poison distribution can be used to approximate the binomial distribution when the sample size n is large. This is then calculated using the formula P(X) = e^-(np) *(np)^x substituting X= 3 P(3)= e^-(430*1.5/100) * (430*1.5/100)^3 P(3)= 0.00158*268.3 P(3) = 0.42 P(3) = 0.0042% P= probability of X occurring given n and p n= sample size p= true probability e= exponential constant ~2.718 X=number of sample successes</span>

The solution for the problem using binomial distribution:
Given:
p = 1.5% or 0.015 
n = 430
Mean = lambda = m = np = 430*0.015 = 6.45 According to Poisson distribution:
P(x) = e^-(np) *(np) ^x Where:
P is the probability of x
n is the sample size
e is the exponential constant
P(3)= e^-(430*1.5/100) * (430*1.5/100)^3 
P(3)= 0.00158* 268.3336125
P(3) = 0.4240%

ankoles [38]

Answer:

The answer is - A. This policy can make coordination with headquarters problematic

This approach is also used to maintain low hiring cost as employing foreigners could cost more. However, this policy has some disadvantages, one of which is that it can make coordination with the headquarters problematic.
