Answer:

$\frac{2}{9}$

Step-by-step explanation:

${\textrm}{Total number of objects here} = 9$

(2 spreadsheets, 3 databases and 4 presentations,

${\textrm}({Total} = 2+3+4 = 9)$

${\textrm}{No. of databases with an odd number} = 2 {\textrm}{(databases with number 1 and 3})$

As not mentioned other wise equal chances of all the outcomes is assumed so, by the classical definition of probability,

P(The chosen item is a odd numbered database)

= $\frac{2}{9}$
