3/16

Explanation:

The following is the punnet square which represents the probabilities of offsprings being produced for this cross:

PR Pr pR pr

PR PPRR PPRr PpRR PpRr

Pr PPRr PPrr PpRr Pprr

pR PpRR PpRr ppRR ppRr

pr PpRr Pprr ppRr pprr

This cross shows that the probability of the offsprings to have white flowers and rounded seeds would be 3/16.
