[AI-generated answer — Bot GPT 3.5]

P(red or blue) = P(red) + P(blue) - P(red and blue)

First, calculate the individual probabilities:
P(red) = 6/16 = 3/8
P(blue) = 4/16 = 1/4

Next, calculate the probability of both red and blue:
There is no overlap between the red and blue marbles, so P(red and blue) = 0

Now substitute the values into the formula:
P(red or blue) = 3/8 + 1/4 - 0
P(red or blue) = 3/8 + 2/8
P(red or blue) = 5/8

Therefore, the probability of selecting a red or blue marble from the bag is 5/8.
