Treating the two Cs as 1, we have 4 letters.

The first letter in the group can be chosen in 4 ways, the second letter in 3 ways and the third letter in 2 ways.

So the total number of ways is 4 x 3 x 2 = 24.

Please correct me if I m wrong, my test is on saturday

7. There are 4 different letters A, b,c(2times) and d.

3 letters can be selected in 2 different ways -

first, when all 3 are different - 4c3=4
second, when 2 of the 3 selected are same = 2c2*3c1 = 3

Total groups = 7.
