kramer

Answer:

Step-by-step explanation:

Mp=$1200

Let sp be x

SP=MP-discount% of MP

x=1200-15/100 * 1200

x=120000-18000/100

x=102000/100

x=1020

the amount of money person saves=MP-SP

=$1200-$1020

=$180

From a club 25 people in how many ways can a group of five members be selected to attend conference? A group of 5 members can be

IgorLugansk [536]

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>
