Option c: 1 / 4

To find the probability of selecting a red or white marble from the bag, we need to add the probabilities of selecting a red marble (9/20) and a white marble (remaining 11/20, since the total number of marbles is 20 and the blue marbles are already accounted for).

Probability of selecting a red marble: 9/20 = 3/8
Probability of selecting a white marble: (11/20) = (11/20) / (9/20 + 11/20) = (11/20) / (20/20) = 11/20

The total probability of selecting a red or white marble is:

(3/8) + (11/20) = (3 + 11)/20 = 14/20 = 7/10

However, the correct option is c, which is 1/4. This is because the probability of selecting a red or white marble is the sum of the individual probabilities divided by the total number of outcomes (20 marbles).

1/4 = (9 + 11)/20 = (20/20) / 20 = 1/20

Therefore, option c is the correct answer.
