The chance of drawing a red marble is equal to the number of red marbles in the bag, divided by the total number of marbles in the bag, or #5/15=1/3#.

There is a total of 15 marbles in the bag and there is an equal chance of drawing any given marble.

The chance of drawing a red marble is equal to the number of red marbles in the bag, divided by the total number of marbles in the bag, or #5/15=1/3#.
