comment Why are these two events not independent?
how do i start a new line? I hit "enter" in the editor but Pr(E) =.51 Pr(F) =.91 E $\bigcap$ F = { HT, TH} = .21 + .21 = .42 $\neq$ Pr(E) $\cdot$ Pr(F) are still on the same line....

comment Probability in flipping a coin
I found another answer and added to the body of my question. What do you think of that?

errr, no not really... do you agree that the answer is 1-p?

one solution manual says $1-p$, the other one says it's $\frac {15}{16}$...x_x

comment Why aren't these events mutually exclusive?
in fact this question is an example that components are independent, but not mutually exclusive =)

@CliveN. independence does not guarantee mutual exclusivity!

what statement implies that it isn't so?

comment Why aren't these events mutually exclusive?
for two events to be mutually exclusive $A_1$ $\cap $ $A_2$ must be nothing. However, I've been told in this question, those two events are not mutually exclusive. I just need some evidence to show that they're not mutually exclusive...

Can you show an approach using hh? Thank you!!!

comment Bayes Theorem confusion… (more complex)
Using this approach we can get away with using 2 events, but I think the reason they used three events is so we can practice with 3 events. theres actually a third part to the problem I will add to the question when I get home. I think we might not be able to get away with 2 events...

thank you Andre, i get it now, can you perhaps take a look at this: math.stackexchange.com/questions/198697/… it's abit more complex version of the Bayes

@AndreNicholas can you explain why we need to ADD the two to get P(E)?

comment Probability question at listing number of outcomes in the sample space.
we just have covered the Method of Inclusion/Exclusion in class today, but the teacher said it'd be easier to get the compliment. that's why he did it this way. How would you approach this problem with the Method of Inclusion/Exclusion? Thank you SOO much for your help!
