Answer:
the probability of choosing is blue marble is less than the probability of not choosing a blue marble
Step-by-step explanation:
the reasoning for this is that there are 50 marbles and only 20 of the 50 are blue. Which means that 30 are not blue. Since 30 is bigger and 20 (ie. there are more non-blue marbles than there are blue marbles), the probability of choosing a blue marble is less than the probability of not choosing a blue marble
