In the case of Standard Normal Distribution, the probability value that a random variable assume a value between 7 and 12 is similar to the probability value that a random variable assume a value from 7 to 12. Why is it so?

Step 1

Normal Distribution is a continuous distribution.

In continuous distribution, random variable can take any value

Step 2

As there are infinite value that the random variable can take

The probability at a specific value is 0

Therefore,

the probability value that a random variable assume a value between 7 and 12 is similar to the probability value that a random variable assume a value from 7 to 12
