Question

For an event b if p (b)=1/2,n (s) = 52 then find n (b).

Answer 1

Answer:

n(b) = 26

Step-by-step explanation:

P(b) = n(b)/n(s)

1/2 = n(b)/52

n(b) = 52/2

n(b) = 26

Answer 2

The value of n(b) = 26

Step-by-step explanation:

Given,

$p(b)=\dfrac{1}{2}$ and $n(s)=52$

To find, the value of $n(b)=?$

We know that,

$p(a)+p(b)=1$

⇒ $p(a)+\dfrac{1}{2}=1$

⇒ $p(a)=1-\dfrac{1}{2}=\dfrac{2-1}{2}$

⇒ $p(a)=\dfrac{1}{2}$

∴ $n(b)=n(s)\times p(b)$

⇒ $n(b)=52\times \dfrac{1}{2}=26$

∴ n(b) = 26

The value of n(b) = 26

Hence, the value of n(b) = 26
