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
