Question

if n(A)=3,p(A)=1\4,then n(S)=?​

Answer 1

Answer:

12

Step-by-step explanation:

p (A) = n (A) / n (S)

1/4 = 3 / n (S)

n (S) = 12

Answer 2

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

Given :

n(A) = 3 and P(A) = 1/4

To find :

The value of n(S)

Solution :

Step 1 of 2 :

Write down the given data

Here it is given that n(A) = 3 and P(A) = 1/4

Step 2 of 2 :

Find the value of P(A)

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

$\displaystyle \sf{ \implies } \frac{1}{4} = \frac{3}{n(S)}$

$\displaystyle \sf{ \implies n(S) = 3 \times 4}$

$\displaystyle \sf{ \implies n(S) = 12}$

Hence the required value of n(S) = 12
