Robert asks?
Can someone help me understand Bernoulli process with probability?
Ok, so someone helped me with this on Yahoo! Answers before and I am still trying to figure it out completely. I only halfway understand it.
So, I think the formula for this is P(x=k) = (nCk)p^k (1-p)^(n-k). If you have a process that consists of 11 trials with a probability of success of 0.3, then:
a) To find the probability of obtaining exactly 5 successes, you would do:
?? What is the C in (nCk) stand for?
P(X=5) = (11C5)(0.3)^5(0.7)^6= ? because I do not know what the C means
b) Find the probability of obtaining at least 8 successes.
So... P(X=8) + P(X=9) +P (X=10) + P(X=11), tells me what?
c) Find the probability of obtaining at most 3 successes?
P(X=0) + P(X=1) +P(X=2) + P(X=3)
Does P = 0.3 and n = 11?
Please help. Thank you so much for your help and patience.

# "?? What is the C in (nCk) stand for?"
It stands for "combination" -- in this case, of "n" things chosen "k" at a time, so the expression "n choose k" for the number of ways of picking "k" events out of "n" events. In your example,
11C5 = 11! ? 5!(11 - 5)!
= (11/1)*(10/2)*(9/3)*(8/4)*(7/5) = 11*3*2*7 = 462
so P(X=5) = 462*(0.3)^5*(0.7)^6 = 0.132

Did you know? Easy 10 pts!?
Spongebob Squarepants, a comical children's cartoon, is actually based on the seven deadly sins. Read and learn:
I have been a fan of SpongeBob Squarepants for years and think that the depth of the characters is one of the things that really makes this show work. Ever since I heard Mr. Lawrence say (in an audio commentary on the Season 1 DVD's) that Stephen Hillenburg based the 7 main characters on the 7 Deadly Sins, I couldn't help but be very fascinated. I think I've figured out which character is each one.
1. Sloth-Patrick
Sloth is the sin of laziness, or unwillingess to act. Obviously this is Patrick. He lays under a rock all the time and doesn't really do anything. In fact in the episode "Big Pink Loser" he got an award for doing nothing the longest.
2. Wrath-Squidward
Wrath involves feelings of hatred and anger. Squidward hates his life, usually hates SpongeBob, and is pretty much angry most of the time.
3. Greed-Mr. Krabs
Obviously Mr. Krabs is greedy and desires money. How could Greed not be Krabs? He actually sang about the power of greed in "Selling Out".
4. Envy-Plankton
Plankton is envious of Mr. Krabs because The Krusty Krab is a success while The Chum Bucket is a failure. His envy drives him to try to steal the Krabby Patty secret formula.
5. Glutony-Gary
I actually think this one is pretty funny. Did you ever notice the running gag in Spongebob where they say "don't forget to feed Gary" or Sponge says "I gotta go feed Gary". Gary even ran away that time when SpongeBob forgot to feed him. Glutony usually refers to the overindulgence of food so I'm guessing this one fits him pretty well.
6. Pride-Sandy
Sandy takes a lot of pride in who she is and where she comes from. She takes pride in the fact that she is from Texas and likes to let everyone know it. She also takes pride in the fact that she is a mammal and a land creature, like in the episode "Pressure" where she tried to prove land critters were better than sea critters.
7. Lust-SpongeBob
Ok, I know what your thinking. It does seem a little weird and curious at first but I have given it a lot of thought. Lust in one definition is "excessive love of others". I think this one works best for Spongebob. He shows his love of others with his overeagerness to do good and help people. If anything is true about SpongeBob its that he loves everyone around him, even if they don't exactly love him back.
See?
Did you know this? Yes or no. Easy ten points.
Larry McCann answers:
You are pretty damn smart for being able to come up with this. Who would have thought that the characters off of Spongebob Squarepants fits so closely to the 7 Sins? It makes sense.
It's almost like with Full Metal Alchemist: Brotherhood, but the 7 sins in Spongebob was unintentional, I think. Spongebob is a loving character, Sandy is a proud character, Gary is usually fed too much for a snail character (well, he certainly can eat a lot anyway), Plankton wants revenge for not being successful, Mr. Krabs makes money in ANY way possible and NEVER spends it, Squidward can never seem relaxed or happy around Sponegbob or any one in particular, and Patrick is the most lazy and dumb character I have ever seen.
I just got one question though.... What's this question doing in the Video Games section? XD
Shouldn't this question be in the Comics & Animations section?
