Are all symmetric distributions normal distributions?
No. There are many other distributions, including discrete ones, that are symmetrical.
Why can a function not be a probability mass function?
A function cannot be a probability mass function (PMF) if it violates the properties of a PMF. A PMF must assign a non-negative probability to each possible outcome of a discrete random variable, and the sum of probabilities for all possible outcomes must be equal to 1. If a function does not satisfy these properties, it cannot be considered a PMF.
What is the probability of winning the lottery depends on how many tickets you buy?
It is a true statement. If you buy them all, the probability of your winning is 1!It is a true statement. If you buy them all, the probability of your winning is 1!It is a true statement. If you buy them all, the probability of your winning is 1!It is a true statement. If you buy them all, the probability of your winning is 1!
What is difference between proportion and probability?
Proportion is the probability of a selected sample. probability is the true probability of all cases. If this is not what you are looking for then please specify.
When probability is not found by considering all possible outcomes but by testing and experimentation it is called probability?
Experimental or empirical probability.
