17!
(17-3)! 3! X .15^3 X .85^17-3
I think this might be asking for the value of the 14th term of the expansion (p + q)17, where p = 0.15 and q = 0.85.
(17!3!×(17−3)!)×0.153×0.85(17−3)=0.2358563915733796
I'm not sure what the question is.
Thanks, Alan....I couldn't make heads or tails of that one......!!!!
I was puzzled at first, but then realised the clue was in the title!
