Answer:

<u>50%</u>

Explanation:

<em>Since</em> it was not a case of a Lettuce seed exposed first to <em>red light</em> and then to <em>far-red light</em> which will very likely not germinate because Pr (chromoprotein inactive form) absorbs red light efficiently, the light absorbed will convert a high proportion of the molecules to the Pfr (chromoprotein active form), thereby inducing germination. So there is a 50/50 percentage chance of of germination.
