<pre>
The probability for the 1st event 

    P1 = P(a plain pencil from the 1st box) = {{{1/10}}}.   (here 10 = 1 + 9 items)



The probability for the 2nd event 

    P2 = P(a colored pencil from the second box) = {{{3/6}}} = {{{1/2}}}.   (here 6 = 3 + 3 items)



The probability that BOTH events happen SIMULTANEOUSLY

    P = P1*P2 = {{{(1/10)*(1/2)}}} = {{{1/20}}}.      <U>Your ANSWER</U>
