If a roan shorthorn is crossed with a white-coated shorthorn, what is the probab

If a roan shorthorn is crossed with a white-coated shorthorn, what is the probability that the offspring will be a roan shorthorn?
So we're supposed to record it from 0-1, rounded.
It's worth noting from the previous question that shorthorn cattle, coat colours may be red, white, or roan. Crosses between a red bull and a white cow produce only roan offspring which shows co-dominance.

So I tried using a Punnett square but I'm confused how to go about solving it, I end up with (R=roan, W=white)
R R
W WR WR
W WR WR
Is this right? And if it is, does that mean 100% of offspring will have roan coats?

Thanks for any help you can provide.
