Answer 2

The best prediction is that you will pick a green marble approximately 7 times and an orange marble approximately 5 times.

Explanation:

If there are 5 orange marbles and 7 green marbles out of a total of 48 marbles, the best prediction for the number of times you will pick a green or an orange marble would still be proportional to the ratio of green and orange marbles.

The ratio of green marbles to the total number of marbles is 7/48, and the ratio of orange marbles to the total number of marbles is 5/48.

To predict the number of times you will pick a green marble, you can multiply the total number of selections (48) by the ratio of green marbles:

48 * (7/48) = 7

Similarly, to predict the number of times you will pick an orange marble:

48 * (5/48) = 5

Therefore, the best prediction is that you will pick a green marble approximately 7 times and an orange marble approximately 5 times.
