Normal distribution is very impotant. So, we should learn its basics. I have made its first video for discussing all about it .

**About Normal Distribution**- It is distribution of continuous series.
- This distribution shows the distribution like 0 to 5, 5-10 and more up to infinite.
- This distribution can be shown as normal distribution curve form for calculating the value of its area that will be between + infinite and - infinite
- For calculating the area we have to calculate value of z first
- Z = X - mean / standard deviation
- Now we calculate the area of Z from table and this will be the probability and its exact value can be calculated by making graph of normal curves.
