lawyer [7]

Answer:

On time: 0.67

Late: 0.33

Step-by-step explanation:

Probabilities

One approach to estimating the probability of occurrence of an event is to record the number of times that event happens (e) and compare it with the total number of trials (n).

The probability can be estimated with the formula:

$\displaystyle P=\frac{e}{n}$

And the probability that the event doesn't occur is

Q = 1 - P

Paulo arrives on time to school e=53 times out of n=79 times. The probability that he arrives on time is:

$\displaystyle P=\frac{53}{79}$

P = 0.67

And the probability he arrives late is:

Q = 1 - 0.67 = 0.33

You know that a number 8 less than 60 is the number 52. so, you could rewrite your answer from the previous part as, "what numbe

svetoff [14.1K]

I'm a little confused by your question.

You said 60-8 = 52 which is true.

Then, you asked 4x = 52 in an integer form
x = 52/4
x = 13. (Is that what you're asking?)

I'm not sure if this helps, but please comment if you need any help! Hope this helps though! :D
