(1)Consider an experiment that has N outcomes e1,e2,…,eN, where it is known that outcome ej+1 is twice as likely as the outcome ej for j=1,2,,N-1.Let Ek=E1,E2,…,Ek. Show that PEk=2k-12N-1

Points j and k plotted on the coordinate grid are two vertices of rectangle jklm rectangle jklm has an area of 7 square units point j is located at 2,1 and point k is located at -5,1 each vertex of the rectangle is located at a point that has integer coordinates. what is the perimeter of rectangle jklm? (need answer asap)
