9) A experiment is a process in which the result cannot be predicted with certain trial a) sure experiment b) random experiment c) equally likely experiment
Answers
Before rolling a die you do not know the result. This is an example of a random experiment. In particular, a random experiment is a process by which we observe something uncertain. After the experiment, the result of the random experiment is known. An outcome is a result of a random experiment. The set of all possible outcomes is called the sample space. Thus in the context of a random experiment, the sample space is our universal set. Here are some examples of random experiments and their sample spaces:
Random experiment: toss a coin; sample space: S={heads,tails} or as we usually write it, {H,T}.
Random experiment: roll a die; sample space: S={1,2,3,4,5,6}.
Random experiment: observe the number of iPhones sold by an Apple store in Boston in 2015; sample space: S={0,1,2,3,⋯}.
Random experiment: observe the number of goals in a soccer match; sample space: S={0,1,2,3,⋯}.
