How to get the index of new number in descending sequence vector

I have probability named A and B

A=[ 0.6 0.2 0.1 0.5 0.5]

B=[ 0.15]

Then the probabilty is arranged and named C

C=[0.6 0.2 0.15 0.1 0.5 0.5]

how can I get to know that probability B is at column 3?

location=find(ismember(C,B))

Note: logical indexing is faster than find
