When practising her tennis serves, the probability that any one of Gemma's serves is in court is 0.3.

Gemma serves 4 times.

Assuming a binomial distribution, calculate the probability that exactly 2 of these serves are in court.

You may use (p+q)4=p4+4p3q+6p2q2+4pq3+q4(p + q)^4 = p^4 + 4p^3q + 6p^2q^2 + 4pq^3 + q^4(p+q)4=p4+4p3q+6p2q2+4pq3+q4.
