The determining of probability will be easier if we can register the whole sample points which form the sample space. From that list we can determine the number of events and the number of members of the sample space and then we are able to determine the probability of the event.
In the rolling of two balance dice at the same time. Suppose K states the event when the sum of the two dice’s eyes that appear is equal to 8. Determine the probability of event K.
The sample space of the rolling of two balance dice is as the following:
the number of members of sample space =36. The number of members of event K=5. The probability of event K→P(K)=5/36.
