Answer 2

Answer:

$\sf{The \ probability \ of \ selected \ pen \ is \ good}$

$\sf{ is \ \dfrac{12}{25}.}$

$\sf{The \ probability \ of \ selected \ pen \ is \ bad}$

$\sf{is \ \dfrac{13}{25}.}$

Given:

• Number of total pens in bag = 50

• Number of good pens = 24

• Number of bad pens = 26

To find:

• Probability of selection of good and bad pen.

Solution:

$\sf{Let \ 'S' \ be \ the \ sample \ space.}$

$\sf{\therefore{n(S)=50}}$

$\sf{(1)}$

$\sf{Let \ A \ be \ the \ event \ of \ selected \ pen \ is \ good.}$

$\sf{\therefore{n(A)=24}}$

$\sf{P(A)=\dfrac{n(A)}{n(S)}}$

$\sf{=\dfrac{24}{50}}$

$\sf{=\dfrac{12}{25}}$

$\sf\purple{\tt{\therefore{The \ probability \ of \ selected \ pen}}}$

$\sf\purple{\tt{ is \ good \ is \ \dfrac{12}{25}.}}$

$\sf{(2)}$

$\sf{Let \ B \ be \ the \ event \ of \ selected \ pen \ is \ bad.}$

$\sf{\therefore{n(B)=26}}$

$\sf{P(B)=\dfrac{n(B)}{n(S)}}$

$\sf{=\dfrac{26}{50}}$

$\sf{=\dfrac{13}{25}}$

$\sf\purple{\tt{\therefore{The \ probability \ of \ selected \ pen \ is \ bad}}}$

$\sf\purple{\tt{ is \ \dfrac{13}{25}.}}$
