Question

if n(A)=3,p(A)=1/4,then n(s)=?​

Answer 1

Answer:

$p(a) = n(a) \div n(s)$

therefore:

$n(s) = n(a) \div p(a)$

then,

$n(s) = \frac{3}{ \frac{1}{4} }$

$n(s) = 3 \times 4 = 12$

Answer 2

Step By Step Answer

P(A) =n(A) ÷ n(S)

1/4 = 3 ÷ n(s)

n(S) = 4×3

[n(S) = 12 ]

This Is The Answer In This Equation
