As you have mentioned in question “unknown color”. It’s a singular, that means all balls are of same color. Now, one ball was picked and it fond to be a red. So, we found one color and it is red. So, probability that all balls are red is 1.(After knowing color of a picked ball, our sample space is shrink to a red from infinite possibilities of colors. )
