Question

A standard number cube is tossed. What is the probability that the number will be less than or equal to 3?

Answer 1

`P(3 " or less on a die") = 3/6 =1/2`

Explanation:

To determine the probability of an event happening, there are two values you need to determine first.

1. 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`.

2. 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.

`"Probability" = "number of desirable outcomes"/"total number of possible outcomes"`

`P(3 " or less on a die") = 3/6 =1/2`

Write a probability as a fraction and give in its simplest form.

Answer 2

`1/2`

Explanation:

assuming that the numbers on the standard number cube are `1-6`, there are `6` possible numbers to get.

the numbers less than or equal to `3`, in the range `1-6`, are `1,2` and `3`.

this means that there are `3` possible numbers to get that are less than or equal to `3`.

probability = number of outcomes possible / total number of outcomes

`3/6 = 1/2`
