$\frac{15}{56}$

Step-by-step explanation:

We have to select george but not nina with two other people

No. of ways selecting 2 two people knowing Geroge will be the third one is

^6C_2 (beacuse we have to exclude Nina)

And total no of ways of selecting 3 people out of 8 people is ^8C_3

Therefore the required Probability is $\frac{^6C_{2}}{^8C_{3}}$

= $\frac{15}{56}$
