 <translate> Number of ways of selecting 3 people out of 10 people = 10C3
In the three members George will always be there in the team. At this step we have vacancy for 2 more members and 9 members are available. Lina cannot be there in the team. So 2 members have to be selected and the number of available members = 9 - Nina = 8
Number of ways to form a 3 member team that includes George and excludes Nina = 8C2
Probability = 8C2/10C3 = 28/120
The final answer: (C). <yor> Nọmba awọn ọna ti yiyan awọn eniyan 3 ninu awọn eniyan 10 = 10C3 Nínú àwọn mẹ́ta tí George máa wà nínú ẹgbẹ́ náà nígbà gbogbo.
