Question 1019117
Five of the 6 accounts 
Probability is 6 (the number of ways it can happen)*(23/47)^5(24/47)=0.0860
-----------------
check
coin toss is almost the same probability
what is the probability of five heads in a binomial of 6 trials
1---6---15---20---15---6---1
That would be 6/64, or 0.09375,  The answer is slightly less than this and the probability is slightly less than half, so it makes sense.
