The number of bit strings of length 10 over the alphabet {a,b,c} have either exactly three as or exactly four bs is given as follows:

28,800.

With three bs, the string is composed as follows:

Then the number of strings with three bs is given as follows:

C(10,3) x 2^7 = 10!/(3! x 7!) x 2^7 = 15,360.

With four bs, the string is composed as follows:

Then the number of strings with four bs is given as follows:

C(10,4) x 2^6 = 10!/(4! x 6!) x 2^6 = 13,440.

Then the total number of strings is calculated as follows:

15,360 + 13,440 = 28,800.
