The probability of continuous distribution is the integral of the probability density function. This probability is called as density. For continuous probability function y-axis represent the probability density function.

? Question : : from the given diagram what is the probability that the x is equals to 4 ??

Answer is not 5 …… why ?? see below:

The question has asked about exact number 4 which is not possible resulting it to 0.

Similarly in order to find the range probability we can use intrgral.
