Question

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

Answer 1

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.
