Question 1011167

a distribution center receives shipments of a product from 3 different factories in the quantities of 50, 30, and 20. three times a product is selected at random, each time without replacement. find the probability that (a) all 3 products came from the third factory and (b) non of the products came from the third factory.
<pre>This is quite similar to a statistics question from Chamberlain College of Nursing</pre>
a) Probability that all three products came from the 3<sup>rd</sup> factory: {{{highlight_green(0.007)}}}, or .7%
b) Probability that none of the three products came from the 3<sup>rd</sup> factory: {{{highlight_green(0.508)}}}, or 50.8%
