If two dice are rolled one time find the probability
a 3 on one die or both dice

Step-by-step explanation:

There are six possible outcomes when rolling a die. Therefore the probability of obtaining a 3 is a given is

.

When throwing the two dice together, the probability of obtaining a 3 is the same:

Since the events are independent then the probability of obtaining a three in both dice is:

.

Finally the probability of obtaining a 3 on a given or both is equal to the sum of the probabilities and

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
