Ok so the wording is confusing
is it
A. 3 friends took 1 slice each (total is 3 slice) or
B. 3 friends took 1 slice total
if A, go to AAAAAA
if B. to to BBBBB
AAAAAAAAAA
3 slices taken
fraction is parts out of whole
what is left
left=original-taken
taken=3
original=8
8-3=5
5=left
fraction is 5/total=5/8
BBBBBB
taken=1
fraction is parts out of whole
what is left
left=original-taken
taken=1
original=8
8-1=7
7=left
fraction is 7/total=7/8
if 3 slices taken total then 5/8 left
if 1 slice taken totl then 7/8 left
Your expected value is 36*2/6 + -36*4/6, which is equal to $-12.
3 - 3√3a
= -----------------
4√8a
3 - 3√3a
= -----------------
8√2a
(3 - 3√3a) √2a
= ----------------------
8 √2a √2a
3√2a - 3a√6
= ----------------------
16a
3(√2a - a√6)
= ----------------------
16a
hope it helps
