Solution

Let S denote the sample space.
Then, n(S) = 52

Let E4 = event of drawing a jack, a queen or a king
       Out of 52 cards, there are four jacks, four queens and four kings.
      i.e. (E4) = 4C1 + 4C1 + 4C1
                      = 4 + 4 + 4 = 12

\[\therefore P\left( E_4 \right) = \frac{n\left( E_4 \right)}{n\left( S \right)} = \frac{12}{52} = \frac{3}{13}\]
