First draw p yellow = 4/7
2nd draw p red = 3/7
3rd draw p red = 3/7
To find the probability of this event (1yellow 2 red - with replacement) we multiply the probabilities.
4/7 x 3/7 x3/7 = 36/343 which cannot be reduced further

Answer:
The answer to your question is the third choice
Step-by-step explanation:
| 1 3 1 | x | 2 -2 |
| -2 1 0 | | 3 5 | =
| 4 1 |
2 x 3 3 x 2 = 2 x 2
Result Multiply rows by columns and simplify
| (1 x 2) + (3 x 3) + (1 x 4) (1 x -2) + (3 x 5) + (1 x 1) |
| (-2 x 2) + (1 x 3) + (0 x 4) (-2 x -2) + (1 x 5) + (0 x 1)|
Simplification
| 2 + 9 + 4 -2 + 15 + 1 |
| -4 + 3 + 0 4 + 5 + 0 |
Result
| 15 14 |
| -1 9|
