Explanation

To find the probability that a point lands in triangle T when randomly placed in the rectangle, we find the ratio of the area of triangle T to the area of the rectangle. The presence of square S does not affect this, since the point is placed anywhere in the rectangle, and we are only asked about triangle T.

Step-By-Step Solution

Step 1

Find the area of the rectangle:

  • Length = 6
  • Height = 4
  • Area of rectangle =6×4=24

Step 2

Find the area of triangle T:

  • Base of triangle T = 3
  • Height of triangle T = 4
  • Area of triangle =21​×base×height
  • Area of triangle T =21​×3×4=21​×12=6

Step 3

Calculate the probability:

  • Probability =Area of rectangleArea of triangle T​=246​
  • Simplify: 246​=41​

Final Answer

The probability that the point lands in triangle T is 41​​ (Option C).
