0.011 or 1/90

Step-by-step explanation:

Since the order of the performances is determined at random the probability of each squad is constant that 1/10

The probability of your squad is 1/10

Given that the first selected was yours (1/10) nine squads are left. Therefore the probability of your friends squad is 1/9.

Hence the probability that your squad performs first and your friend's squad performs second is (1/10 * 1/9) 1/90 or 0.011
