Deuce to Seven Triple Draw Questions

[paulish]

I've been reading up on Negreanu's chapter in SS2. And I wondered if any of you guys could help me out with some numbers here:

<font color="red"> Q1 </font> How many unique 5 card combination are possible

<font color="red"> Q2 </font> How many pat 7 &amp; 8 hands are there?

<font color="red"> Q3 </font> How many "one card 7 &amp; 8 draw"-hands (excluding 8 draws with a straight draw) are there?

<font color="red"> Q4 </font> How many hands are there in total in the following Two-Card Draw groups:
a) 234, 235, 237, 245, 247 &amp; 257?
b) 236, 246, 256 &amp; 267?
c) 247, 248, 357, 358, 367 &amp; 457?

<font color="red"> Q5 </font> How many Three card draw hands are there (23, 24, 25 &amp; 27)?
