Question 429566
The shell thickness of eggs is Normally distributed 
with a mean of 0.38mm and a standard deviation of 0.03mm. 
(iv) If two eggs were selected at random how likely is it that both would have a shell thickness of at least 0.41mm?
-----------
Find P(one of the eggs has thickness >= 0.41)
---
z(0.41) = (0.41-0.38)/0.03 = 1
P(x >= 0.41) = P(z>= 1) = 0.1587
----
P(2 of the eggs >=0.41) = (0.1587)^2 = 0.0252
