### HideShow timer Statistics

There are 3 red chips and 2 blue chips. When arranged in a row, they form a certain color pattern, for example RBRRB. How many color patterns are possible?

What is wrong with my solution?
total no of patterns possible = 3! *2! =12

Ans 10.

Question is saying number of pattern possible. Ur solution also includes similar patterns. For example. RRBBR, RRBBR,

So I guess the solution could be 5!/3!*2!= 10.

What is OA?
