Answer:

²⁵C₅ = 53130

Step-by-step explanation:

number of people in the club = 25

number of people to be selected in the group to attend conference = 5

number of ways of selecting this group from 25 people is same as selecting 5 objects from 25 distinct objects = ²⁵C₅ (Selection)

= \frac{25!}{5!(25-5)!}

= \frac{25!}{5!(20)!}

= 21×22×23×5

= 53130

∴ <u>Number of ways of selecting this group from 25 people = 53130</u>
