Step-by-step explanation

We are asked to get the probability of rolling either a 2 or 6 in a single dice

To do so, we will make use of the probability definition:

Probability simply means the ratio of possible outcomes to the total number of outcomes

In our case

we have a dice, so the total outcome will be {1,2,3,4,5,6}

to roll a 2, the possible outcome is {2}

to roll a 6, the possible outcome is {6}

Thus, the probability of rolling a 2 will be


(1)/(6)

The probability of rolling a 6 will be


(1)/(6)

Therefore, the probability of rolling a 2 or 6


\begin{gathered} P=(1)/(6)+(1)/(6) \\ \\ P=(1+1)/(6)=(2)/(6)=(1)/(3) \end{gathered}

In per cent, we will have


(1)/(3)*100=33.33\text{ \%}

To the nearest whole number, we will have 33%
