She randomly picks up 5 articles of clothing..1 out of 5 are clean.

This example follows Binomial distribution.

And, Standard deviation of binomial distribution is given by,

Here, n = 5 and p = 20% = 0.20

So, Standard deviation is given by,

So, Standard deviation = 0.8944

and distribution is BINOMIAL DISTRIBUTION.
