<p>72.
Right?</p>
<p>If solid card are to be in the second from the left:</p>
<p>4 possibilities in the first spot, 3 possibilities in the third spot, 2 possibilities in the fourth spot.
4<em>3</em>2 = 24</p>
<p>If solid card are to be in the middle:</p>
<p>4<em>3</em>2 = 24</p>
<p>If solid card are to be in the second from the right:</p>
<p>4<em>3</em>2 = 24
24+24+24 or 24*3= 72</p>
<p>Or simply…</p>
<p>Left End: 4 possibilities since solid is excluded
Right end: 3 possibilities since solid is excluded
Second from the left : 3 possibilities since solid in included now
middle: 2 possibilities
second from the right: 1</p>
<p>Ahh ok i understand now thank you and yes 72 was correct</p>
