Given:
The measure of length QR is 6.
The measure of length ST is 12.
The objective is to find the probability that point k lies on QR.
The formula to find the required probability is,
[tex]P(K)=\frac{measure\text{ of lenth ST}}{measure\text{ of length QR}}[/tex]
Substitute the given values in the above formula.
[tex]\begin{gathered} P(K)=\frac{6}{12} \\ =0.5 \end{gathered}[/tex]
Hence, the probability that the point k lies on QR is 0.5.
