Answer

92 percent is transmitted through the pane of glass.

Work Step by Step

We know that 96 percent is transmitted through the first surface. Then, 96 percent of that amount is transmitted through the second surface. $$(0.96)(0.96) = 0.9216$$ We calculate that 92.16 percent is transmitted through both surfaces of the glass.
