Answer 2

The probability of getting a factor of 2 is $\dfrac{1}{3}$.

Step-by-step explanation:

The factors of 2 are 1 and 2. In a dice there are numbers from 1,2,3,4,5 and 6. The probability of getting an event is given by :

$P(E)=\dfrac{\text{no of favorable outcomes }}{\text{total no of outcomes}}$

Here, total number of outcomes are 6 and the favorable outcomes are 2 i.e. 2 and 2.

So, the probability of getting a factor of 2 is given by :

$P(E)=\dfrac{2}{6}=\dfrac{1}{3}$

So, the probability of getting a factor of 2 is $\dfrac{1}{3}$.
