Question

A number line contains points Q, R, S, and T. Point Q is on the coordinate 24, R is on the coordinate 28, S is on the coordinate 29, T is on the coordinate 42. Find the probability that a point chosen at random on QT is on ST. Express your answer as a percent.

Answer:Probability = 72.2%

Step-by-step explanation:A number line contains points Q, R, S, and T with coordinated 24, 28, 29, and 42 respectively.

Now if a point lies on QT then the length of QT= coordinate of T – coordinate of Q

= 42 – 24

= 18

If a point lies on ST then the length of ST = coordinate of T – coordinate of S

= 42 – 29

= 13

Now we know Probability of an event =

Probability =

= 72.2%

Therefore,

probability that a point chosen on QT will lie on ST will be 72.2%Answer:72%

Step-by-step explanation:QT has length 42-24 = 18.

ST has length 42-29 = 13.

The length ST is 13/18 ≈

72.2%of the length of QT.
