How Much Do Clicks Wobble?

A marketing team sends out $200$ emails. The emails behave independently of one another, and for each single email:

• it is opened with probability $0.15$;
• if it is opened, it then leads to a click with probability $0.20$;
• an email that is never opened can never be clicked.

Let $X$ be the number of the $200$ emails that end up clicked.

What is the standard deviation of $X$?

Round to two decimal places.
