Troy has a number cube with the numbers
Remember that the probability of any event is:
There is only one way to roll a
and there are six possible outcomes on any given roll.
Knowing this, can you write the probability of rolling a
P(rolls an odd number)
How many odd numbers are there from
P(rolls a factor of
There are four factors of
: , , , and .
That means there are four possible successes.
Thus, the probability of rolling a factor of
is or .
