Answer 2

Answer:

Probability of getting multiple of 3 on the upper surface of the die is : $\sf \dfrac{1}{2}$

Step-by-step explanation:

Step 1 : Express the outcomes :

Multiple of 3 in a die are : 3 & 6

Total numbers in a die are : 1, 2, 3, 4, 5, & 6

Step 2 : Calculate the required probability :

We know that,

${ \underline{ \boxed{ \sf {probablity = \dfrac{favourable \: outcomes}{possible \: outcomes}}}}}$

Where,

• Favourable outcomes is 2 i.e., 3 & 6
• Possible outcomes is 6.

So, probability of getting multiples of 3 in a die is :

$\sf \to probability = \dfrac{2}{6} \\ \sf \to probability = \frac{1}{3}$

$\therefore \bf Required \: probability = \dfrac{1}{2}$
