One may get the white ball and the red ball – in whichever order?
There are four identically sized and shaped balls in a box, with only its top open. Each ball is of a different colour, these being: Green, Red, White and Blue, only one ball of each colour. Without looking into the box, one ball is randomly picked out and tis color is noted; then it is returned to the box. What are the chances that, in two successive draws, one may get the white ball and the red ball – in whichever order?
