Probability is the chance of something happening. Probability describes whether an
event is likely to happen, unlikely to happen, certain to happen, impossible, or more

Any function of a random variable X is also a random variable.
For example, H(X) is a function of X (and X is a random variable) then H(X) is also a
random variable.
Also kth moments about mean of a random variable X are calculated as:

Example:
The names of 5 men and 5 women are written on slips of paper and place in a hat. Four names
are drawn. What is the probability that 2 are men and 2 are women?
Solution:
N = Number of units in the population = 5 men + 5 women = 10
n = Number of un

If we want to consider the raw data then our first step will be to arrange the data in
ascending order of magnitude, then:
The median is the middle value of the data set.
The lower quartile (Q1) is the first quartile of the data set.
