Miyu is giving out 9 identical chocolates to her 7 friends, including Dhruv.  All possible distributions are equally likely.  What is the probability that Dhruv gets exactly 2 chocolates?

stars and bars

15C7 = 6435 possible outcomes

 

Give Dhruv her 2 chos,

now you have  6 friends and 7 chocolates

12C6 = 924 favourable outcomes

 

924/6435 =  28 / 195    =approx  14% chance
