- The applications of normal distribution related to the biological decision making situations.

##### 11.1 INTRODUCTION

This chapter deals with the probability distributions for continuous random variables, which can take any value in a given interval. This can be expressed as smooth curves, where the probabilities are expressed as areas under the curve.

##### 11.2 DEFINITION OF NORMAL DISTRIBUTION

It is a most important continuous distribution ...
