What are the key characteristics of a Binomial Distribution?
It has a fixed number of trials, fixed probability of success, two outcomes (success or failure), and each trial is independent.
What does P(X=r) represent in the context of a Binomial Distribution?
It represents the probability of getting exactly r successes in n trials.
What is the formula for calculating the probability in a Binomial Distribution?
P(X=r) = C(n, r) * (p^r) * ((1-p)^(n-r)), where C(n, r) is the combination of n trials taken r at a time.
In Binomial Distribution, what does 'n' represent?
'n' represents the fixed number of trials.
In Binomial Distribution, what does 'p' represent?
'p' represents the fixed probability of success on each trial.
What are the two possible outcomes in a Binomial Distribution?
Success or failure.
What does it mean for trials to be independent in a Binomial Distribution?
The outcome of one trial does not affect the outcome of another trial.
