Question: In a box of 12 light bulbs, it is known that 5 of them are defective. That is, 5 are defective and 7 function properly. We select 2 bulbs from the bag at random, without replacement. Find the probability they both function properly. Show work. Round your answer to 3 decimal places.

We are given that: in a box of 12 light bulbs, it is known that 5 of them are defective.
Thus Number of defective = 5 and Number of functioning properly = 12-5=7
2 bulbs are selected from the bag at random, without replacement.
We have to find: the probability that they both function properly.
That is we have to find:
P(X = 2) = …….?
X : Number of bulbs function properly
