Assuming that the selection process was done without replacement, the probability of selecting two white mugs without replacement is 1/28
<h2>Given data</h2>
Sample Space
Red mugs = 4
yellow mugs = 8
white mugs = 2
Sample Size = 4+8+2 = 14
We are going to assume the selection was done with out replacement
Hence the probability of selecting the first white mug is
<em>Pr(W1) = 2/8 = 1/4</em>
<em>The probability of selecting the second white mug is </em>
<em>Pr(W2) = 1/7</em>
<em />
Hence the probability of selecting two white mugs one after another
= 1/4*1/7
=1/28

This is how I would do it;
Convert to minutes 3/5 *60 = 36
Convert this to decimal 2/5 = 0.4
Then;
if it takes 36 mnts to paint 0.4yd^
in 60 mnts x yd^
___________________
60 x 0.4 / 36 = 0.66666667
convert back to fraction = 2/3 yd^ in 1hr
<span>Unless you have some other choices, I'd have to say Stratification, to make sure the groups are representative and heterogeneous.
I hope I helped.</span>
