Question

If p[A] = 3/13 n [ s] = 78 then what is the value of n [A]? solve​

Answer 1

$\tt\Huge{\color{magenta}{Solution:-}}$

$\begin{gathered} \: P(A) = \frac{n(B)}{n(S)} \\ \\ p(A) = \frac{n(B)}{52}\\ \\but P(A) =\frac{3}{13} \\ \\ \therefore\:n(B) = \frac{3 \times 78}{13} \\ \\ \:n(B) = 3 \times 6\\ \\ \huge \blue { \boxed{ \:n(B) = 18}}\end{gathered}$
