Answer:

4.5%

Step-by-step explanation:

1) red = 3
2) green = 4
3) blue = 5

Total bumper cars: (3 + 4 + 5) = 12 cars

Michelle gets red car:

  • 3/12 = 1/4

Remaining red cars: 3 - 1 = 2

Remaining total cars: 12 - 1 = 11

Garth get red car:

  • 2/11

Probability they both get red cars:

  • 1/4 × 2/11 = 1/22 ≈ 4.5%
