permutationa and combination help watch

1. 2 bottles of soft drink and 5 bottles of juice are selected from 5 different bottles of soft drink and 12 different bottles of juice. The bottles selected are arranged in a row. How many arrangements can be made? My answer is 5C2 x12C5 x 7!. Why it is wrong?
Many thanks.

I don't know where you've got that answer from, but it's incorrect.

Correct answer is 5C2 x12C5 x 7! = 39 916 800
5. Oh. That will be great.
950400 is the answer from the test paper. It is a multiple choice question and there is no choice for 39916800.
May be the question is wrong. I should ask my teacher for the marks. Thanks a lotttt.
