a punnet square is a four box grid, and you put each individual probability on the outside of each box, so your answer for a punnet square consisting on Pp, and Pp would be the following probabilities: PP, Pp, Pp, pp. Here is a helpful video: ''Learn Biology: How to Draw a Punnett Square'' - all credits to the owner.
