on Practice Describe each of the following events as impossible, unlikely, as likely as not, likely, or certain.
a. Gavin rolls an even number on a number cube.



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.
