15.)

We know that in a symmetrical curve the area on either side of the central value is equal for a certain interval.

We know that the total area under the curve is equal to 100%.

Now, in a symmetrical distribution curve, the area under 1 sigma covers 68% ,

the area under 2 sigma covers 95% ,

and area under 3 sigma covers 99.7%,

Here we have to find an area less than .

So, we get:

*NOTE:- Denoted decimal in the above diagrams are actually in percentage, not decimals.

Thus, an area less than is
