A product is an assembly of 5 different components. The product can be sequentially assembled in two possible ways. If the 5 components are placed in a box and these are drawn at random from the box, then the probability of getting a correct sequence is
1
\(2 \over 5!\)
2
\(\frac 2 5\)
3
\(\frac {2}{(5\ -\ 2)!}\)
4
\(2 \over (5\ -\ 2)!\)
