Question 73015
A company ships computer components in boxes that contain 30 items. Assume that the probability of a defective computer component is 0.2. Use the geometric variance to find the variance of the defective parts.
---------
The probability distribution is binomial because each item is either 
defective or not.
variance = sqrt(0.2*0.8*30)=2.19
