There are 18c4 ways that RSM wants to send 4 of its 18 teachers into a conference. that means there are 3060 ways to send
there are 18 teachers and RSM wants to send 4 mem out of 18
so, we use combinatorics for this
Combinatorics is the branch of Mathematics dealing with the study of finite or countable discrete structures. It includes the enumeration or counting of objects having certain properties. Counting helps us solve several types of problems such as counting the number of available IPv4 or IPv6 addresses.
It is used to find solutions easily for possible ways of a problem
For that we are using the formula for combinatorics
NCr = n!/ (r! (n – r)!)
similarly 18c4 = 18!/ (4! (18 – 4)!)
= 3060
Therefore , there are 3060 ways that RSM wants to send 4 of its 18 teachers into a conference.
