The figure shown is a rhombus.
which equation is true regarding the angles formed by the
diagonals and sides of the rhombus?
x + y = z
2x = y + z
oz + x = 2y
2x + 2y =4z

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18}, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
