Question

two fair number cubes are rolled at the same time. what is the probability that both number cubes have the number four facing up? thanksss <3333

Answer 1

The probability that both number cubes have the number 4 facing up is 1/36.

Explanation:

For a cube, we have the number:

1,2,3,4,5 and 6

The number 4 only occurs once in the six.

So, the probability of having the number 4 in a single roll is 1/6.

Now, for two rolls, we have two probabilities which we will have to multiply.

Thus, we have the probability as:

`(1)/(6) * (1)/(6) = (1)/(36)`
