A standard number cube is tossed. What is the probability that the number will be less than or equal to 3?
To determine the probability of an event happening, there are two values you need to determine first.
How many possible outcomes are there altogether?
In this case with a toss of the die, there are
#6#outcomes, being the numbers from #1#to #6#.
Of the possible outcomes how many of them will meet our conditions? IN this case we want a number equal to or less than
#3#, ... the numbers #1,2,3#. There are #3#desired outcomes.
Write a probability as a fraction and give in its simplest form.
assuming that the numbers on the standard number cube are
the numbers less than or equal to
this means that there are
probability = number of outcomes possible / total number of outcomes
