Well, I am only 17 and I do belive in God and in spirits.
I used to go to a private school when I was in the 5th grade and our one friend did a report on Witchcraft, she had a books on it to work on at school. The books would have spells and chants and all sorts of things. We went in the restroom, turned all the lights off and said some of those things just as the book said to do. We didn't know any better.
That night I just remember being on the phone with one of my friends that did it and we were TERRIFIED of going to sleep. That night I had my little sis sleep with me, both of us had the same dream about some witch chasing us.
Now I do not have any of those bad dreams but I feel when I'm alone that something dark is there haunting me. When I pray, thoughts are always interferred with bad things about God and they are uncontrollable. I read somewhere that doing things like ouija boards and other things can cause evil spirits into your life and I wonder if this is happening to me?

Determine if both sides of the following expressions are equivalent.

f(x1; x2; x3) = NOT(x1)x3 + x1x2NOT(x3) + NOT(x1)x3 = x2NOT(x3) + x1NOT(x3) + NOT(x1)x2x3

NOT being the equivalent to the opposite so like if x1 was true, then NOT(x1) would be false

I know that there is laws of physics. Such as, water boils when you reach x temperature and water freezes when you reach y temperature. BUT, do we know why water boils at a certain temperature and freezes at a certain temperature? Or not yet...??

A) What is the probability that exactly 5 deals are required?
B) What is the probability that 5 or fewer deals are required?
C) What is the probability that exactly 3 deals were required, given that 5 or fewer were required?
I assumed A) was 13/48 using the conditional probability
P(5th is heart | first 4 are not hearts) = P (5th is & 1,2,3,4 are not) / P(1,2,3,4 are not) and those cancel so it equals P(5th).
I am not sure if I am doing this right, so I need more help.
