Find the number of distinguishable permutations of the given
letters "AAABBBCC".

If a permutation is chosen at random, what is the probability
that it begins with at least 2 A's?

That's the probabilility that a randomly chosen one is "AA" 
followed by a distinguishable permutation of the letters "ABBBCC".
There are  of these.

So the probability is that 60 times out of 560 one of those
will be chosen.  That's  or ths of the
time.
