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 = \frac{\text{Favorable event}}{\text{Total possible events}}\times 100

    Probability = \frac{13}{18}\times 100

                      = 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.
