Stats Binomial Distribution

Question 1

Bioko all distributor

Answer 1

If you work it out, the branches that happen happen to follow pascal triangle, and then the rest is straightforward

Want 3 6s in 3 rolls?

It would be how many times this repeats which is 3c3
X the probability calc in this row
Which is 1/6 ^3 that’s it

Generalise is
TrialsChooseDesired x success ^desired success. X failure ^desired failure (which is 1- success) which is just trials- desired

Question 2

Rules for when binomial disturb it on can be used

Answer 2

• that n trials are INDEPENDENT
• that inky two outcomes = success and failure
• AND THAT THE PROBABILITY OF THESE ARE BOTH FIXED

Question 3

Also how to determine the form

Answer 3

Make sure to have WORKED OUT PROBABILTIY IF SUCCES SEPARATLEY and then out in

Like orisbilty if having 3 girls = 1/8

But in one family probability of having 3 girls would be x =3, and probability if succes is just having a girl =0.5

Question 4

Funliative probikty

Answer 4

This is just the probability if it being 5 4 3 2 and 1m so all

So if they say like up to 5 that’s what

Here if itdless than = then calculator calm
If it’s more than need to do 1- p of something ekse

Question 5

What is the expectation of binomial probability?

How to find most likely chance

Answer 5

It’s n x probability by

This is by lit entering all the values and finding their probabilities and seeing the highest

Feature if s binomial distribution I’d thst there is ONLY ONE PEAK

Thus if it is rising to a peak then starts falling , it is thst peak!
A good estimate is using the expectation !

Question 6

What does mean mean

Answer 6

Expectation too
