Answer :
Using probability we can say that the event that Gavin rolls an even number on a number cube is as likely as not.
Probability is the study of chance. The likely chance that an event can occur in a random experiment written as a fraction is called probability.
Probability of a event is calculated as the ratio of the favorable outcomes of an event to all the possible outcomes of the event.
Given as experiment: A number cube is rolled by Gavin.
Event : An even number comes up on the face of the cube.
Favorable outcomes : {2,4,6} = 3 outcomes
Total outcomes or sample space: {1,2,3,4,5,6} = 6 outcomes
Probability that an even number comes up:3/6=1/2
Probability that an even number does not come up=1-1/2=1/2
From the above probabilities we see that :
P(even)=P(not even)=1/2
Hence the Gavin rolls an even number is as likely as not likely.
