Edugain Q&A

probability


There are 3 books belonging to 3 students. The books were put into a box, and each student pulls out a book one after the other. What is the probability that each student gets his or her own book

in this answers are

a. 3/3                                        b. 1/6                                                 c. 2/6                                               d. 1/2

and answer is b 

but according to me the answer should be c 

because there are only 3 students 

abd if we bring 2/6 in simplest form then ans will be 1/3 which according to me should be the right answer

hey can you reply my doubt is not clear yet

 

hello is any one answering to questionins or not

 

TOTAL NUMBER OF BOOKS IS = 3

NUMBER OF WAYS THE BOOKS PUT IT IN THE BOX IS = 3FACTORIAL = 3*2*1=6

PROBABILITY OF EACH STUDENT GET HIS BOOK = 1/6

That is the correct answer for me.
