Answer:
The probability is 26/77
Step-by-step explanation:
First, we calculate the probability of selecting a red ball.
To do this, we sum up the number of balls at first = 6 + 3 + 13 = 22 balls
The probability of selecting a red ball is 13/22
We now want to select two red balls without replacement.
The first probability is 13/22 while the second will be 12/21 since it is without replacement.
The final probability of both would thus be 13/22 * 12/21 = 156/462 = 26/77
