Question

Suppose there are $11$ slots in a Hash Table. At an instant there are $5$ empty slots and a new element $x$ is inserted in Hash Table. What is the the probablity that new element fits without collision?

I think it should be $\frac{5}{11}$ but answer given says :::

EDIT :: Actual question is

Answer 1

Given number of free slots available = 5

  Total number of slots  =  11

  So probability that collision will not occur on insertion  = n(Favourable outcome) / n(Total outcome)

                                                                                 = n(free slots) / n(total slots)

                                                                                 = 5 / 11

Hence 5 / 11 is correct..

Comments

habib you are wrong ...5/11 is the probabilty of choosing a free slot among the 11 slots

but when you want to insert a key without collision you must insert it in one of the five free slots which gives probability of 1/5

But bro actually the thing is the key may be anything..It is  not  fixed..So it may go to any of the entries of the table..

So how r u guaranteeing that only 5 slots will be total outcome??

So what is the correct answer guys ? 5/11 or 1/5???

5/11 is correct
