The probability of choosing a blue marble is 3/10 as there are 3 blue marbles out of a total of 10.

The probability of choosing a white marble is 2/10(1/5) since there are 2 white marbles out of 10.

The probability of choosing an orange marble is 1/10 given that there is 1 orange marble out of 10.
