Distribution

Question 1

Conditions of binomial distribution

Answer 1

There are a fixed number of trials.
There are two possible outcomes (success and failure).
There is a fixed probability of success.
The trials are independent of each other.

Question 2

Uniform distribution

Answer 2

When the probabilities of all outcomes are the same, eg. a fair dice

Question 3

Normal distribution formula

Answer 3

Z = (x - µ) / σ

Where Z is the outcome of typing mean = 0 and standard diviation = 1 into inverse normal

Question 4

Formula to help with inverse binomial distribution

Answer 4

(1 - p)^n = probability (x = 0)

where n is the number of trials
and where p is the probability of success

Question 5

Normal distribution conditions

Answer 5

n is large
p is close to 0.5
