A bag contains 8 balls of which 5 are red and 3 are white.
If a man selects 2 balls at random from the bag,
what is the probability that he will get one ball of each colour?
~~~~~~~~~~~~~~~
The number of all possible different pairs of balls is = 4*7 = 28.
The number of pairs with different colors is 5*3 = 15.
Therefore, the probability under the problem's question is . ANSWER
