7/2 is the probability of an event. Explain.


The probability of an event E is defined as the number of outcomes favourable to E divided by the total number of equally likely outcomes in the sample space S of the experiment.

P(E) = Number of Favourable Outcomes/ Total Number of Outcomes

P(E) = n(E)/n(S)

Number 7/2 cannot be the probability of an event because the probability of any event always lies between 0 and 1.

  • The entire possible set of outcomes of a random experiment is the sample space or the individual space of that experiment.
  • The likelihood of occurrence of an event is known as probability.
  • The probability of occurrence of any event lies between 0 and 1.
