There are 6 brown, 5 blue, and 2 orange marbles in a hat. what is the probability of picking two orange marbles in a row without returning the marbles back to the hat?

The total number of marbles = 6 + 5 + 2 = 13 marbles

Orange= 2 marbles

The probability of getting the first marble out of the hat is

2 / 13

The probability of getting the second marble out of the hat is

1 / 12  The total has been reduced by one  and the number of orange marbles has been reduced by one.

2/13 * 1/12 = 2 / 156 = 1/78
