Question 1192684
.
A box contain 10 black {{{highlight(cross(marble))}}} <U>marbles</U>, 8 white {{{highlight(cross(marble))}}} <U>marbles</U> and 6 yellow {{{highlight(cross(marble))}}} <U>marbles</U>. 
If a ball is drawn at random, what is the probability of getting black marble and white marble?
~~~~~~~~~~~~~~~



The problem says that &nbsp;ONE &nbsp;ball is drawn at random,


but the question asks about probability of getting two balls, &nbsp;black and white.
