Answer: The probability of Sandra choosing a blue marble is 2/9, the probability of choosing a yellow marble is 5/9, and the probability of choosing a white marble is 2/9.

Explanation:

There are a total of 2 + 5 + 2 = 9 marbles in the bag.

The probability of Sandra choosing a blue marble is 2/9 because there are 2 blue marbles out of 9 total marbles.

The probability of Sandra choosing a yellow marble is 5/9 because there are 5 yellow marbles out of 9 total marbles.

The probability of Sandra choosing a white marble is 2/9 because there are 2 white marbles out of 9 total marbles.

The sum of these probabilities is equal to 1, as Sandra must choose one marble and it must be one of the available options:

2/9 + 5/9 + 2/9 = 9/9 = 1
