9514 1404 393

Answer:

  1/14

Step-by-step explanation:

The probability of drawing the first red ball is 10/36, the number of reds divided by the number of balls.

The probability of drawing the second red ball is 9/35, the remaining number of reds divided by the remaining number of balls.

  P(2 red) = (10/36)(9/35) = 1/14
