Question

if n(a)=3 p(a)=1/4 then n(s)=?​

Answer 1

$12$

Step-by-step explanation:

$Given, \: \: n(a) = 3 \: \: \: and \: \: \: p(a) = \frac{1}{4} \\ we \: \: know \: \: that \: \: \boxed{p(a) = \frac{n(a)}{n(s)} } \\ Now, \: \: \frac{1}{4} = \frac{3}{n(s)} \\ \: \: \: \: \: \: \: \: \: \: n(s) = 3 \times 4 \\ \: \: \: \: n(s)= 12$
