Binomial Distribution

what is a probability distribution

a list of all possible outcomes togteher with their pronbabilites

pascual triangle

probabilites pasual triangle

what is success written as

s

what is faliure written as

q

notation

B(n,p)

what is n

trials

what is p

probability of success

what conditions need to be met to calculate binomial distribution

• the number of trials is fixed

• the trails are independant

• there are two possible outcomes for each trail (success and faliure)

what is the mean for binomial distribution B(n,p)

np
