(i) P(white or red) = 6/10 = 0.6
(ii) P(not red) = 4/10 = 0.4
(iii) P(blue or red) = 6/10 = 0.6
(iv) P(white) = 2/10 = 0.2
(ii) P(not red) = 4/10 = 0.4
(iii) P(blue or red) = 6/10 = 0.6
(iv) P(white) = 2/10 = 0.2

AAAaannndd the bot gets it wrong yet again!
2 each of blue and white, so
P(w|r) = P(b|r) = (6+2)/10 = 4/5
2 each of blue and white, so
P(w|r) = P(b|r) = (6+2)/10 = 4/5
