Answer 2

Given : The probability of getting an item defective is 0.005.

To Find : the probability  that exactly 3 items in a sample of 200 are defective.

Solution:

Using Normal Distribution :

The probability of getting an item defective is 0.005

p = 0.005

1 - p = 1 - 0.005 = 0.995

n = 200

x= 3

P(x) = ⁿCₓpˣ(1-p)ⁿ⁻ˣ

=> P(x) = ²⁰⁰C₃(0.005)³(0.995)¹⁹⁷

=> P(x) =  0.06116

the probability  that exactly 3 items in a sample of 200 are defective. is 0.06116

or using position distribution

np = 200 * 0.005 = 1  = Mean

λ = 1

P(x)  = λˣ  e^(-λ) / x!

P(3) = 1³ e⁻¹/3!  

= e⁻¹/6

= 0.3679/6

= 0.061316
