Question

Point K on ST is chosen at random. What is the probability that K lies on QR?s

Answer 1

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,

`P(K)=\frac{measure\text{ of lenth ST}}{measure\text{ of length QR}}`

Substitute the given values in the above formula.

`\begin{gathered} P(K)=(6)/(12) \\ =0.5 \end{gathered}`

Hence, the probability that the point k lies on QR is 0.5.
