A die is rolled, what is the probability that a 3 or a 6 is obtained? P (3 or 6) = ___

Step-by-step explanation:

The sample space in a  3  times die roll  =63=216.  

Now,  P(getting at least one 6)=1−P(getting NO 6).  

Probability of getting no  6  in a single die roll

=56.  

Thus probability of getting NO  6  in three die rolls

=56×56×56=125216.  

Therefore, the probability of getting at least one  6  

P=1−125216=91216.
