Abox contains 24 light bulbs, of which two are de- fective. if a person selects 10 bulbs at random, without replacement, what is the probability that both defective bulbs will be selected?

Total light bulbs = 24

Defective bulbs = 2

Non defective bulbs = 22

The probability of selecting 10 bulbs with two defective bulbs

We will use combination formula which states:

=

=

=

= 0.16

Therefore, the probability that both defective bulbs will be selected is 0.16

its definatley   this on your answer choice?
