Question

If p(A) =3/4, n (A)=39,find n(s)​

Answer 1

Answer:

n(S) = 52

Step-by-step explanation:

p(A) =3/4,

n (A)=39

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

3/4= 39/n(S)

n(S) = 39×4/3

= 13×4

= 52

n(S) = 52

Answer 2

If P(A) = 3/4 , n (A) = 39 then n(S) = 52

Given :

P(A) = 3/4 , n (A) = 39

To find :

The value of n(S)

Solution :

Step 1 of 2 :

Write down the given data

Here it is given that P(A) = 3/4 , n (A) = 39

Step 2 of 2 :

Find the value of n(S)

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

$\displaystyle \sf{ \implies \: \frac{3}{4} = \frac{39}{n(S)}}$

$\displaystyle \sf{ \implies \: n(S) = 39 \times \frac{4}{3} }$

$\displaystyle \sf{ \implies \: n(S) = 52 }$

If P(A) = 3/4 , n (A) = 39 then n(S) = 52
