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