What is the probability that a rolled dot cube will stop with exactly two dots on top?

Answer 1

20

Answer 2

The probability of rolling a dot cube and stopping with exactly two dots on top is 1/6, because there are 6 possible outcomes when rolling a dot cube (1, 2, 3, 4, 5, 6) and only one of those outcomes has two dots on top.

Answer 3

One out of six.

Note that this question is easier to think of if you use a more familiar name for the object, e.g. a "rolled die", not a "rolled dot cube". Many textbook publishers use the phrases "dot cube" or "number cube" to avoid associating the material with gaming, though the question becomes more intuitive when written "what is the probability that you will roll a 2 on a normal 6-sided die?"
