A bag contains 6 black and 8 white balls. One ball is drawn at random. What is the probability that the ball drawn is white?

Solution (By Examveda Team)

$$\eqalign{ & {\text{Let}}\,{\text{number}}\,{\text{of}}\,{\text{balls}} \cr & = \left( {6 + 8} \right) \cr & = 14 \cr & {\text{Number}}\,{\text{of}}\,{\text{white}}\,{\text{balls}} = 8 \cr & P\left( {{\text{drawing}}\,{\text{a}}\,{\text{white ball}}} \right) \cr & = \frac{8}{{14}} = \frac{4}{7} \cr} $$
