Answer 2

If n(A) = 4, n(S) = 12 then P(A) = 1/3

Given :

n(A) = 4, n(S) = 12

To find :

The value of P(A)

Solution :

Step 1 of 2 :

Write down the given data

Here it is given that n(A) = 4, n(S) = 12

Step 2 of 2 :

Find the value of P(A)

$\displaystyle \sf{ P(A) = \frac{n(A)}{n(S)}}$

$\displaystyle \sf{ \implies P(A) = \frac{4}{12}}$

$\displaystyle \sf{ \implies P(A) = \frac{1}{3}}$
