what's wrong with these statements?

  1. A probability distribution specifies the probabilities of the possible outcomes of a randon variable. 2. In a binomial probability distribution, each observation has only two possible outcome that are mutually exclusive. 3. A discrete uniform distibution, the simplest of all probability distributions, is the distribution of equally likely outomes. Cheers…

A probability distribution specifies the probabilities of ALL possible outcomes of a DISCRETE randon variable. In a binomial probability distribution, each INDEPENDENT observation has only two possible outcome that are mutually exclusive. A discrete uniform distibution, the simplest of all probability distributions, is the distribution of PROBABILITIES OF equally likely outomes. otherwise they look right to me~

I saw a question like this and it was which statement was INCORRECT and the 4th one said that the Normal dist was discrete when it’s actually continuous. Can you tell us the question and the 4th option?

“A discrete uniform distibution, the simplest of all probability distributions” So what makes a probability distribution “simple”? Is a normal distribution simpler or more complicated than an exponential distribution?
