Hi,
You do understand the concept of TOTAL, that's a start
1) 10,  2) 10, 3)32
Probability is {{{Particular/TOTAL}}}, P(1st event <u>and</u> 2nd event)= {{{P(1st event)* P(2nd event)}}} 
1)<u>w/o replacement</u> P(2nd yellow given 1st green) = {{{(6/10)(4/9)}}}
2) a)<u>replacement</u> {{{(6/10)(5/10)}}}, b) {{{(6/10)(5/9)}}}<u>w/o replacement</u>
3) a)0r{{{12/32 + 16/32}}} b){{{  16/32 + 13/32 - 5/32}}}P(A or B) = P(A) + P(B) - P(A and B)
4) p(def) = 3/12 = .25, draw 5   a) {{{.75^5}}}  b){{{ 1 - .75^5}}}
