Comfi Cabs always has five taxis working at the same time.

Each working taxi is either available or not available.

At any time, the probability that a taxi is not available is 0.4.

Find the probability that exactly two of the five taxis are available at the same time.

You should use part of this equation

\[(p + q)^5 = p^5+ 5p^4q + 10p^3q^2+ 10p^2q^3+ 5pq^4+ q^5\]

Give your answer to 2 decimal places.
