नगर परिषद् में चार पुरुष व छ: स्त्रयाँ हैं। यदि एक समिति के लिए यादृच्छया एक परिषद् सदस्य चुना गया है तो एक स्त्री के चुने जाने की कितनी संभावना है ?

A

$\frac{3}{5}$

B

$\frac{3}{5}$

C

$\frac{3}{5}$

D

$\frac{3}{5}$

Solution

There are four men and six women on the city council.

As one council member is to be selected for a committee at random, the sample space contains $10(4+6)$ elements.

Let A be the event in which the selected council member is a woman.

Accordingly, $n ( A )=6$

$\therefore P ( A )=\frac{\text { Number of outcomes favourable to } A }{\text { Total number of possible outcomes }}=\frac{n( A )}{n( S )}=\frac{6}{10}=\frac{3}{5}$
