a = $\frac{3}{10}$ , b = $\frac{4}{5}$

Step-by-step explanation:

P(red) = $\frac{red (marbles)}{total(marbles)}$

= $\frac{30}{30+50+20}$

= $\frac{30}{100}$

= $\frac{3}{10}$ simplified

P(not white) = $\frac{red + blue(marbles)}{total(marbles)}$

= $\frac{30+50}{30+50+20}$

= $\frac{80}{100}$

= $\frac{4}{5}$ simplified
