A bin contains 67 bulbs of which 8 are defective.
If 15 light bulbs are randomly selected from the bin without replacement, find the probability that all the bulbs selected are good ones?

Hello
The total combinations in which we can select good ones is
52C15=4.48*10^12
total ways in which we can select 15 is
67C15 = 3.45*10^14
Just divide
4.48*10^12/3.45*10^14
This would give you the answer
Hope this helps
With Regards
