Answer 1

To find the probability of randomly selecting a striped blue marble, we first need to find the total number of blue marbles and the total number of striped marbles.

Total number of blue marbles = 12
Total number of striped marbles = 81

The number of marbles that are both blue and striped = 17

Therefore, the probability of randomly selecting a striped blue marble is:

P(Blue AND Striped) = (Number of blue AND striped marbles) / (Total number of marbles)
P(Blue AND Striped) = 17 / 107

Therefore, the probability of randomly selecting a striped blue marble is 17/107.
