<p>Total arrangements of 4 tricks from 6 = <sup>6</sup>P<sub>4</sub> = 6 × 5 × 4 × 3 = 360</p>

<p>Now, arrangements where the two specific tricks are together:</p>

<p>Choose 2 more tricks from the remaining 4 = <sup>4</sup>P<sub>2</sub> = 12</p>

<p>Now arrange the 4 tricks, with the two fixed tricks together.</p>

<p>Treat them as one block.</p>

<p>Arrangements = 3! × 2! = 6 × 2 = 12</p>

<p>Total unwanted ways = 12 × 12 = 144</p>

<p>Required ways = 360 − 144 = 216</p>
