0.329

Step-by-step solution

4 steps

  1. Identify the total number of trials and the number of times Paulo arrived on time from the previous problem.

    Total number of days = 79
    Number of times Paulo arrived on time = 53

  2. Calculate the number of times Paulo arrived late.

    Number of times Paulo arrived late = Total number of days - Number of times Paulo arrived on time
    Number of times Paulo arrived late = 79−5379 - 53
    Number of times Paulo arrived late = 26

  3. Calculate the probability of Paulo arriving late.

    P(arrives late)=Number of times Paulo arrived lateTotal number of daysP(\text{arrives late}) = \frac{\text{Number of times Paulo arrived late}}{\text{Total number of days}} P(arrives late)=2679P(\text{arrives late}) = \frac{26}{79}

  4. Express the probability as a decimal (optional).

    P(arrives late)≈0.329113...P(\text{arrives late}) \approx 0.329113...

    Rounding to three decimal places:

    P(arrives late)≈0.329P(\text{arrives late}) \approx 0.329

    The estimated probability that Paulo arrives late is 2679\boxed{\frac{26}{79}} or approximately 0.329\boxed{0.329}.
