Question

5 लड़के और 4 लडकियाँ एक ही पंक्ति में बैठे हैं इसकी
कितनी संभावना है कि सभी चार लडकियाँ साथ-साथ बैठी हैं?​ ​

Answer 1

Answer:

5760

Step-by-step explanation:

since all boys will be standing together so they will be considered as single packet. similarly, all girls will be standing together so they will be also considered as a single packet . Hence we have to arrange these two packets so there will be 2 possible ways for arranging them. Now inside the packet the boys can arrange themselves in n factorial ways so for ways total arrangement possible will be 5!=120 and same for girls will be 4!=24

Hence the total arrangements possible are 2! * 5! * 4! = 2*120*24 =5760
