0.8
The total number of marbles in the jar is 8 (red) + 5 (blue) + 3 (green) = 16 marbles.
The probability of selecting a blue marble is the number of blue marbles divided by the total number of marbles:
5 blue marbles / 16 total marbles = 0.3125 (approximate to 0.33)
Therefore, the approximate probability of selecting a blue marble is 0.33.
