एक परीक्षण में $2$ बच्चों वाले परिवारों में से प्रत्येक में लड़के-लड़कियों की संख्याओं को लिखा जाता है।

यदि हमारी रूचि किसी परिवार में लड़कियों की संख्या जानने में है तो प्रतिदर्श समष्टि क्या होगी ?

Option A
Option B
Option C
Option D

Solution

since the maximum number of children in each family is $2,$ a family can either have $2$ girls or $1$ girl or no girl.

Hence, the required sample space is $S =\{0,1,2\}$
