Question 910743
A Poisson experiment examines the number of times an event occurs during a specified interval.
What is a binomial experiment? 

A binomial experiment has the following characteristics:
◾ The experiment involves repeated trials. 
◾ Each trial has only two possible outcomes - a success or a failure. (def, not def
◾ The probability that a particular outcome will occur on any given trial is constant. 
◾ All of the trials in the experiment are independent.

Using {{{P (8)= highlight_green(nC8)(p^8)(q)^(n-8) }}} 
p and q are the probabilities of def and not def respectively. 
n = how many shipped
{{{nCx = (n!)/x!(n - x)!)}}}
