I was hoping someone would be able to check my working and advise my if I have made a mistake in this stats problem!
There are 50 balls in a bag and 10 are blue. 5 balls are taken out of the bag, and what is the probability none of the removed balls are blue.
(40/50) * (39/49) * (38/48) * (37/47) * (36/46) = 0.31~
Just wanted to check if this is correct.. been ages since I have done any stats!
Thanks a lot.

I would also agree that it is correct.
