Answer:

3/5

Step-by-step explanation:

The probability of an event is the ratio between the number of favourable cases and probable cases.

Probable cases: how many different papers can be drawn: 5, since there are 5 names

Favourable cases: how many draws satisfy event C: 2 because out of the 5 names only three have less than five letters (David and Sarah have exactly 5 so they should not be included).

Probability of event C=2/5
