The probability of the four cards being spades\mathrm{=\frac{{ }^{13} C_2}{{ }^{52} C_2} \times \frac{{ }^{11} C_2}{{ }^{50} C_2}}

Similarly, for other suits.

\therefore The required probability \mathrm{=4 \times \frac{{ }^{13} C_2 \times{ }^{11} C_2}{{ }^{52} C_2 \times{ }^{50} C_2}=\frac{44}{85 \times 49}}
