Answer:
0.375
Step-by-step explanation:
The left bag has 2 blue marbles and 2 not blue marbles
The chance of drawing a not blue marble is 2/4 = 0.50
The right bag has 1 blue marble and 3 not blue marbles
The chance of drawing a not blue marble is 3/4 or 0.75
Drawing one marble from each bag results in a probability of
0.50(0.75) = 0.375 of getting no blue marbles at all.
