You can put this solution on YOUR website! A group of 8 children is chosen from a class with 30 boys and 10 girls. what is the probability that the group contains at least one boy
--------------
P(at least one boy) = 1 - P(no boy)
---------
P(at least one boy) = 1 - [10C8/30C8]
----
P(at least one boy) = 1 - 45/5852925 = 0.000007688...
