Use Pascal’s triangle to find the possible value(s) of nn if nC3=(n3)=20.

Expert Solution

I guess u want to find n such that nC3=20 using pascal triangle. and this is the only soln. Bcoz if u write the next few rows of pascal triangle and observe each of the 4 th number of each row after 6th tgey are all greater than 20 and the value keep on increasing also.
