What does discrete distribution mean?
Discrete distributions refer to probability distributions where the random variable can only take the value of countable numbers.
If two events are mutually exclusive, what is the probability of both events occurring simultaneously?
Mutually exclusive events cannot occur together, so the probability of both events occurring simultaneously is 0

What does continuous distribution mean?
Continous distribution refers to a probability distribution in which the random variable can have any value in a certain interval or range.
In a binomial distribution, what are the two parameters that determine the shape of the distribution?
The binomial distribution is determined by the number of trials and the probability of success in each trial

What does the expected value and variance refer to?
Expected value is essentially the mean, the average of all the possible outcomes. Variance is the measure of the spread of a specific probability distribution.
What is the expected value of a discrete probability distribution?
The expected value of a discrete probability distribution is the weighted average of all possible outcomes, where the weights are the probabilities of each outcome
