Imagine you have a bag of candies that have different colors such as blue, red, and green. You close your eyes and pick one candy from the bag. The candy that you picked represents a sample point.
A sample point is just a fancy way of saying the outcome of an experimental event or trial. It can be anything from picking a candy from a bag, throwing a dice, spinning a wheel or flipping a coin.
It is important to define sample points in statistics because they help us understand the possible outcomes of a particular event or experiment. By looking at all the possible sample points, we can also figure out the probability of each outcome happening.
