Question

Concept of probability and basics laws frm biological discussion

Answer 1

Introduction to Probability:

Probability means possibility or likelihood for the occurrence of a specific event, as for example, the likelihood of winning the cricket match. If several events are taking place, the possibility for the occurrence of any specific event can be predicted.

Thus, if a coin is tossed 100 times, it is likely that it will fall “head” 50 times and “tail” 50 times because chances for turning up of head and tail are equal, i.e., 1:1. When an experiment results in two or more different results, the experiment is called trial and the results obtained from the experiment are called events.
