Question

(2) For an event B if P(B) = 1/2,
n(S) = 52 then find n(B).
​

Answer 1

Answer:

Step-by-step explanation:

To Find? :-

n(B)=?

​Answer:-

⇒ We have already given that,

     

$\implies\bold{1)\ P(B) = \large\frac{1}{2} \ , \ 2) \ n(S) = 52}$

$\implies Using \ the \ formula,$

$\implies\bold{ P(B) = \large\frac{n(B)}{n(S)} }$

$\implies \large{ \frac{1}{2} = \frac{n(B)}{52} }$

$\implies \large n(B) = \frac{1}{2} . 52$

$\implies \boxed{n(B) = 26}$
