Question

The probability of getting a composite number on the throw of a dice is:

• A. $\frac{1}{3}$
• B. $\frac{5}{6}$
• C. $\frac{1}{2}$
• D. None of these

Answer 1

Answer: (A)

$\frac{1}{3}$

On a through of a dice $6$ possible outcomes are possible.

The are $\{1,2,3,4,5,6\}$. Among which only $4$ and $6$ are composite numbers i.e. two numbers are composite.

Now from the definition of probability, the probability of getting a composite number on the throw of dice is $\frac{2}{6}=\frac{1}{3}$.
